UKPA : Bondage clue to spy's death

Bondage clue to spy's death

UKPA | December 22, 2010

Mystery death spy Gareth Williams visited a series of bondage websites in the months before his death at his London flat, police have revealed.

The 31-year-old MI6 codebreaker viewed sites showing people bound and tied, which included do-it-yourself guides.

Detectives also found a £15,000 collection of unworn women's designer clothing, including tops, dresses and shoes in his wardrobe.

They revealed he visited a drag cabaret in east London four days before his death and held tickets to two more. One witness has also come forward to say he was at a popular gay bar in Vauxhall several months before his death.

Mr Williams's decomposing body was found in a padlocked holdall in the bath of his Pimlico flat on August 23. The keys were inside. Detective Chief Inspector Jackie Sebire, who is leading the inquiry, said she is convinced someone else helped put him in there. She said police believe they will get to the bottom of the intensely private spy's death by studying his private life.

Speaking at New Scotland Yard, she said: "We remain completely open-minded about how he died. We are appealing today to someone who is out there to come forward and tell us more."

The GCHQ code-breaker, who had been on secondment to the spy agency, was found dead by police after concerns were raised for his welfare. The mysterious circumstances of Mr Williams's death sparked an international frenzy of speculation.

No evidence of drugs, alcohol or poisons were found during a battery of tests conducted by toxicologists. Mrs Sebire revealed that police have forensic evidence that other people were in the flat, whom they have not been able to trace.

She added that an expert, brought in to examine the red North Face holdall Mr Williams was found in, concluded he could not have locked it. The zip was held shut by a common travel-style Yale padlock through holes in two zip fasteners.

Tests found the temperature inside the bag would have risen to 30C within three minutes. An expert on survivability in confined spaces from the National Policing Improvement Agency (NPIA) said he would have suffocated in 30 minutes. Mr Williams, of Anglesey, North Wales, was last seen alive on August 15, eight days before he was found dead in the £400,000 property.

BBC : Dead MI6 spy Gareth Williams 'visited bondage websites'

Dead MI6 spy Gareth Williams 'visited bondage websites'

December 22, 2010

An MI6 spy found dead in a padlocked holdall in his central London flat had accessed bondage websites several times, police have revealed.

Gareth Williams, 31, from Holyhead on Anglesey, had also visited a drag show and owned £15,000 worth of women's designer clothing, detectives said.

Mr Williams' naked body was found at his Pimlico flat in August.

Police believe other people helped the MI6 codebreaker to get into the holdall and want to speak to them.

Officers have released e-fit images of a couple who they said visited Mr Williams' Alderney Street home in June or July.

The Met said disclosure of "embarrassing, hurtful and distressing" details was necessary to get some information as detectives believe "someone else was in the flat".

Det Ch Insp Jackie Sebire said: "We know he was intensely private, and however difficult this might be for someone who has had any interaction with Gareth, it would really help us if they came forward so we know if that side of his life had any relevance to his death.

"If he was alive, he got into it voluntarily or, if not, he was unconscious and placed in the bag," she added.

Police revealed Mr Williams viewed websites showing people bound and tied, which included do-it-yourself guides.

The two e-fit images issued by police show a casually-dressed couple of Mediterranean appearance, thought to be in their 20s, who were buzzed through the communal entrance of his home by another resident in late June or July.

The GCHQ code-breaker, who had been on secondment to the spy agency, was found dead by police after concerns were raised for his welfare.

No evidence of drugs, alcohol or poisons were found during a series of tests conducted by toxicologists.

Det Ch Insp Sebire revealed police had forensic evidence that other people were in the flat, whom they have not been able to trace.

She added that an expert, brought in to examine the red holdall in which Mr Williams was found, concluded he could not have locked it.

The keys were found inside the bag.

She said experts had said the temperature inside the bag would have risen to 30C (80F) within three minutes and he would have suffocated inside half-an-hour.

Fashion design courses

The detective added Mr Williams probably died in the early hours of 16 August, a week before he was found.

He had a collection of six boxes of unworn designer clothing in a wardrobe, she said.

Mrs Sebire said Mr Williams attended two fashion design courses at Central St Martins College in 2009 and 2010, and said the items could have been related to those diploma courses.

The detective said although a witness had reported seeing Mr Williams in a gay bar, police do not know for certain he was gay.

She said Mr Williams occasionally spent between 30 minutes and an hour on bondage sites, but added there was no evidence that he was "obsessed" with bondage and no other pornography was found.

Police also revealed that the spy visited a drag cabaret in east London four days before his death and held tickets to two more.

Det Ch Supt Hamish Campbell said investigators were sure someone else involved with the bondage or gay scene had "linked in" with Mr Williams but police "cannot find that trace".

The death remains suspicious and unexplained and no conclusive cause has been found.

An inquest will be held at Westminster Coroner's Court on 15 February.

Police have asked anyone with information to call the incident room in Hendon on 020 8358 0200. If the caller wants to remain anonymous, he or she could contact Crimestoppers on 0800 555 111.

Telegraph : MI6 spy Gareth Williams was a child prodigy whose private life was kept secret from closest friends and family

MI6 spy Gareth Williams was a child prodigy whose private life was kept secret from closest friends and family

By Victoria Ward | December 22, 2010

Gareth Williams, the MI6 spy who was found dead in a bag in his bath, was a child prodigy.

He took a maths GCSE at primary school and A-levels at 13, graduating with a first from Bangor University by the age of 17.

He went on to study advanced mathematics at Cambridge, eventually leaving because he felt he had learned all he could.

Williams grew up in Anglesey, north Wales. A quiet child from a tight-knit family, whose great passion was cycling.

Friends said that despite his extraordinary mathematical mind, he was "very naive about people". He was a loner, with few social contacts, even among his work colleagues. He struggled to make friends after being catapulted into the company of older people at an early age.

Dylan Parry, 34, from Anglesey, said he was an isolated child. "He never really made friends, either his own age or from those younger than him,” he said.

“He didn't have any of the normal childhood interests or pursuits of teenagers. His only real interest was maths. He was obsessed with his subject. Socially he was very awkward but very nice."

By the time he left Cambridge, Williams’ potential had already been spotted by GCHQ scouts.

In 2001, he took at job as a code expert at the GCHQ "doughnut" building in Cheltenham, working alongside hundreds of mathematicians, cryptologists and analysts going on to develop techniques to speed up data encryption.

For the first time, it is likely Williams felt challenged and comfortable in his surroundings, working with like-minded people in a top-secret environment that suited his personality.

His sparse bedsit was immaculate and devoid of personal belongings and clutter. His former landlady, Jenny Elliot, 71, said that “his life was his work”.

In 2003, Williams spent six months at Menwith Hill, the RAF station in Yorkshire and in 2006 he spent time at Fort Meade in Maryland, home of the United States’ National Security Agency, GCHQ’s partner in global surveillance.

He is also reported to have made a number of visits to Afghanistan.

Last year, he was seconded to the London headquarters of MI6, a sign of his steady progress up the hierarchy at GCHQ.

The 31-year-old was assigned to live at 36 Alderney Street, in Pimlico, central London, an MI6 safe house.

Williams died before he could take up his next post in the Cyber Security Operations Centre at GCHQ, his intensely private personality meaning that the circumstances surrounding his mysterious death are baffling detectives three months on.

BBC : Talented MI6 spy Gareth Williams 'never spoke of work'

Talented MI6 spy Gareth Williams 'never spoke of work'

December 22, 2010

An MI6 spy who was found dead in his central London flat was a talented young man who was close to his family, but would never speak to them about his work.

Gareth Williams, 31, from Holyhead on Anglesey, north Wales, was found dead in a padlocked holdall in his central London flat in August.

The death remains suspicious and unexplained with no conclusive cause found.

Mr Williams regularly went home to north Wales to visit his family.

His parents, Ian and Ellen, live in Valley, Anglesey, while his father works at Wylfa nuclear power station. His grandmother and grandfather lived in Holyhead.

His uncle, William Hughes, said his nephew had never spoken about his work.

"He was very, very talented," he added.

"He would never talk about his work and the family knew not to ask really."

Mr Williams' academic talent was evident at an early age, when he was a pupil at Bodedern Secondary School in Anglesey.

His maths teacher Geraint Williams said he had been an "exceptional" pupil.

'Very modest'

"He was probably not the best mathematician I have seen, but the best logician," he said.

"If you explained something once, he remembered it, you didn't have to explain it again."

While he was a secondary school pupil, Mr Williams was also being coached at Bangor University and graduated with a first class degree in maths at just 17.

In 2000, he took a postgraduate certificate in mathematics at St Catharine's College, Cambridge.

He was then offered a job at the Government Communications Headquarters (GCHQ) in Cheltenham.

"It didn't surprise me at all that he was very interested in codes and ciphers," Geraint Williams said.

"It didn't really surprise me that he was recruited by GCHQ."

Mr Williams worked as a communication officer at GCHQ before being sent on secondment to MI6 for a year.

The head of MI6 Sir John Sawers described Mr Williams as a "highly talented person" who was "very modest and generous as well".

He added that Mr Williams had done "really valuable work with us in the cause of national security".

Mr Williams grew up as a keen cyclist and joined Holyhead Cycling Club when he was 17.

Keith Thompson, from the club, said: "He was a really lovely young man.

"We were club mates but Gareth wasn't the sort to go to the pub after a race, so he didn't have any close friends in the group.

"It was his cycling that we knew about. He was known for being very good on hill races but a couple of times he won the club's 'best all-rounder' award."

An inquest will be held at Westminster Coroner's Court on 15 February.

Murdered spy used bondage sites and kept female outfits worth £15,000

December 22, 2010

AN M16 codebreaker whose decomposing body was found zipped inside a holdall in his flat visited bondage websites in the months before his death, police have revealed.

Gareth Williams viewed webpages showing people bound and tied, which included do-it-yourself guides.

Detectives also found a 15,000 collection of unworn women's designer clothing, including tops, dresses and shoes in the 31-year-old's wardrobe.

They revealed he visited a drag cabaret in east London four days before his death and held tickets to two more.

One witness has also come forward to say he was at a popular gay bar in Vauxhall several months before his death.

Police also released two e-fits of a couple who they said were visiting Mr Williams's Alderney Street home in late June or July.

The casually-dressed Mediterranean couple, in their twenties, were buzzed through the communal entrance by a neighbour.

They suggested they had been given a key by "Pierre Palo" and were on their way to flat four.

Mr Williams's body was found in a padlocked holdall in the bath of his Pimlico flat on 23 August. The keys were inside.

Detective Chief Inspector Jackie Sebire, who is leading the inquiry, said she is convinced someone helped put him in there. She said police believe they will get to the bottom of the intensely private spy's death by studying his personal life.

Speaking at New Scotland Yard, she said: "We remain completely open-minded about how he died.

We are appealing to someone who is out there to come forward and tell us more."

The GCHQ codebreaker, who had been on secondment to the spy agency, was found dead by police after concerns were raised about his welfare.

The mysterious circumstances of his death sparked a frenzy of speculation.

No evidence of drugs, alcohol or poisons were found during a battery of tests conducted by toxicologists.

Mrs Sebire revealed the police have forensic evidence that other people were in the flat who they have so far been unable to trace.

She added that an expert, brought in to examine the red North Face branded holdall Mr Williams was found in, concluded he could not have locked it himself.

The zip was held shut by a common travel-style Yale padlock through holes in two zip fasteners.

Tests found the temperature inside the bag would have risen to 30C within three minutes.

An expert on survivability in confined spaces from the National Policing Improvement Agency (NPIA) said Mr Williams would have suffocated in 30 minutes.

Mrs Sebire said Mr Williams probably died in the early hours of 16 August, a week before he was found. She said there was no sign of injury, apart from bruising to his elbows, which might have taken place some time before his death.

Mr Williams, of Anglesey, North Wales, was last seen alive on 15 August, eight days before he was found dead in the 400,000 property.

Speaking about his private life, Mrs Sebire said a collection of six boxes of unworn designer clothing were found in a wardrobe. She said items by Stella McCartney, Christopher Kane, and Louboutin had been bought at London boutiques and online.

The senior detective said the clothing was in various sizes, all small, and a number of women's wigs were also found.

But she added there was no evidence that Mr Williams was "obsessed" with bondage and no other pornography was found.

Metro Police : E-fits issued in death investigation

E-fits issued in death investigation

Bulletin 0000002137 | December 22, 2010

OFFICERS from the Homicide and Serious Crime Command investigating the circumstances into the death of Gareth Williams (date of birth 26.09.78) in August continue to appeal for information.

Police have issued two e-fits of a man and a woman they wish to speak with in connection with the enquiry.

They are described as of Mediterranean appearance, aged between 20-30 years-old.

They called at 36 Alderney Street, Pimlico, SW1 late one evening in June or July, 2010.

Having gained access to the communal area of the building, they intimated that they had a key to Gareth's flat, number 4, and were last seen walking towards it. It is believed they said they had been given the key by a 'Pier Paulo', or something similar.

At this stage, officers are making a further appeal and are urging this man and woman to come forward and assist, so that they can be eliminated from our enquiries.

There are also a number of other points on which officers are asking the public for their help.

Gareth was attending Central St Martins College, Clerkenwell, on a fashion course for beginners - police are urging anyone who knew or met him through the course to come forward if they have any information.

In addition, Gareth's wardrobe contained a collection of female attire, such as dresses and shoes, which were new, and seemingly unused, worth in the region of £15,000, as well as a collection of wigs. If anyone knows where, or when he might have bought such clothing, officers would very much like to speak to them.

Police would also like to hear from anyone who met Gareth on a visit he made to a drag cabaret - 'Bistroteque' in Mile End on 13 August 2010. Gareth had bought tickets for two other shows at the same venue. They also want to speak to anyone who saw Gareth in May 2010, at the 'Barcode' gay bar in Vauxhall, south London, when there was an unconfirmed sighting of him.

Routine forensic examination of Gareth's phones has revealed a limited number of occasions when access was made from them to websites relating to bondage and escape from bondage. Officers would like to talk to anyone who had contact with Gareth via one or more of those sites, who may be able to assist in understanding the circumstances of his death.

Police strongly believe Gareth was not alone in his flat at or before the time of his death and are strongly urging any person, or persons who were there, or knows anything in relation to this, to come forward.

DCI Jacqueline Sebire, the investigating officer, said today: "Gareth was a very private individual, and we know he would not have given his keys to anyone other than close family. I am asking this man or woman, or anyone who recognizes them, to encourage them to come forward and assist us with this enquiry.

"Gareth's death remains suspicious and unexplained, and enquiries into the circumstances continue."

Anyone with information should call the Incident Room in Hendon on 020 8358 0200 or, if they wish to remain anonymous, Crimestoppers on 0800 555 111.

The Williams family said today: "Gareth's family are still struggling to come to terms with the loss of their son and brother, they urge anybody to come forward with any information that can assist the police investigation."

The Inquest into Gareth's death will be heard before Westminster Coroner's Court on 15 February 2011.

Gareth Williams returned to the UK from a planned holiday in the US, on Wednesday, 11 August 2010. CCTV enquiries established that on a number of occasions on his return, he was shopping in the West End and Knightsbridge areas.

CCTV images issued by officers (6 September 2010) showed Gareth on Saturday 14 August 2010 at approx 15:00hrs, entering Holland Park underground station.

On Sunday 15 August 2010 Gareth was shopping in Brompton Road, SW7. He went to a cash machine, and then into Harrods. At approx 14:30hrs, CCTV images show him in Hans Crescent, SW1 heading towards Sloane Street, near to the Dolce and Gabbana store.

He was wearing a red t-shirt, beige trousers, and white trainers. Gareth was approx 5ft 7inches tall, with short hair and of a muscular build.

On 23 August 2010, Gareth was found in his flat at Flat 4, 36 Alderney Street, Pimlico, SW1 by uniformed officers. There was no sign of any forced entry to the property, and no signs of disturbance inside.

Gareth was found unclothed, in a zipped and padlocked red 'North Face' holdall which was in an empty bath in the en suite bathroom. Officers do not believe any property was missing from the flat and there was no suggestion the items within the flat were specifically posed. No drugs, or indications of drug usage, were recovered.

The first post mortem on 25 August 2010 established no cause of death. Further examinations of the body were held and results from comprehensive further toxicology tests carried out came back negative, showing no trace of any drugs, alcohol, poisons or any other substances that would indicate cause of death.

This Is London : Spy in bag: Police seek mystery couple, MI6 man used bondage websites

Spy in bag: Police seek mystery couple, MI6 man used bondage websites

Justin Davenport, Crime Editor | December 22, 2010

Police revealed dramatic details today about the bizarre death of an MI6 spy found in a sports bag - and appealed for help to find a mystery couple who may hold vital clues.

Scotland Yard issued the first images of a man and woman who could make clear how Gareth Williams died.

The couple visited the spy's Pimlico flat several weeks before his decomposing body was found, on August 23, in the bath inside a zipped and padlocked North Face bag. Detectives also revealed:

* The 31-year-old codebreaker had a collection of designer dresses and shoes worth £15,000 in his flat. The clothes by Stella McCartney and Christopher Kane, and Louboutin shoes, appeared unworn, with many still in wrappings.

* He was almost certainly not alone when he died and had bruised elbows, possibly as he tried to escape from the bag. A pair of keys to the padlock were inside under his body.

* He had visited five bondage websites since last year. No pornography was found in the flat. He visited a comedy drag night at a club called Bistrotheque in Mile End on August 13.

* He had passed two fashion design courses at Central Saint Martins.

* He had four mobile phones including some that were pay-as-you-go.

Tests have been unable to explain how Mr Williams died. One theory is that he may have been the victim of a sex game that went wrong.

Police told how they employed a specialist to climb into the North Face holdall and re-enact events that might have led to his death. He found it was impossible to shut the bag and padlock it from inside without help. It was also impossible to unlock the bag from inside on his own.

The mystery couple called at the flat in Alderney Street in June or July. They buzzed the outside door and were let in by a woman on the ground floor. They told her they were visiting flat 4 — Mr Williams's — and had their own key, given to them by someone called “Pier Paulo”, or a similar name.

The couple went upstairs and did not come down, suggesting they entered the flat. They were aged in their twenties or thirties, possibly of Mediterranean or east European appearance.

Despite a number of previous appeals the pair have not come forward and detectives increasingly believe they could hold vital clues.

Detective Chief Inspector Jacqueline Sebire, leading the inquiry, said: “Gareth was a very private individual. We know he would not have given his keys to anyone other than close family. I am asking this man or woman or anyone who recognises them to encourage them to come forward and assist us.”

In a statement, Mr Williams's family said: “We are still struggling to come to terms with the loss of their son and brother, we urge anybody to come forward with any information that can assist the police investigation.”

At the time of the visit, Mr Williams is believed to have been away and detectives say it is highly unlikely he gave his keys to anyone. Tests on his body show he was not poisoned, drugged or under the influence of alcohol at the time of his death. There were no injuries to suggest a struggle and an examination of his computers showed he had a secret fetish for bondage and being confined in enclosed spaces.

There was no evidence of anything missing from his flat and no signs of a disturbance. Detectives have discounted one rumour that the flat was locked from the outside.

Mr Williams, a keen cyclist, was in London on a year's secondment and was due to return to the GCHQ government listening post in Cheltenham. He is known to have made trips on business to the US but he was not a field agent and his spy bosses can find no reason for him to have been killed.

He was last seen eight days before his body was found. CCTV showed him at Harrods and Holland Park Tube.

Anyone with information can call 020 8358 0200 or ring Crimestoppers anonymously on 0800 555111.

The unanswered questions

How did he die?

A post mortem has proved inconclusive. But experts can say he was not stabbed or shot, there are no obvious injuries to his body and tests found no trace of alcohol, drugs or poison. It is possible he suffocated inside the North Face bag. Experts say that because of the heat in the flat he could have died within minutes if he could not escape.

Was he alone and why did he not escape from the bag?

Police now believe he was almost certainly not alone. Intriguingly, there is no sign of anyone else being in the flat, but tests have shown that Mr Williams could not have locked himself into the bag on his own. He must have had help and either climbed into the bag as part of a sex game — or, in some way, was forced in. The real question is why he was unable to escape and why the second party did not help him. One possibility is the second man — or woman — left the scene planning to return but when they did the spy was already dead. The second person then panicked and fled. The puzzle is why he or she did not leave any clues. And why, if the explanation was innocent, they have not come forward.

What about his private life?

This remains a mystery. Inquiries have found the spy to be an intensely private individual. He was spotted in a gay bar near the MI6 HQ in Vauxhall and visited a transvestite bar in the weeks before he died but there is no other obvious reference to his sexuality. His computers revealed a interest in bondage and a colourful wig was found in his flat along with £15,000 of high fashion women's dresses and shoes, all of which seem to be still in their wrappers. But there were few, if any, friends who knew him personally.

What was he doing before he died?

His body was found on August 23. It is known he returned from a trip to the US on August 11 and was last seen alive at Holland Park Tube station on August 14 and shopping in Harrods the following day. The post mortem results suggest he died soon afterwards but his body was not found until eight days later.

Who are the mystery couple? 

This is one of the most tantalising questions in the inquiry. No one — including MI6 or his family — can explain why Mr Williams would have given his keys to anyone. They were specific about visiting Flat 4 though they are not thought to have mentioned the spy by name. The codebreaker is not believed to have been in the flat at the time — and the possibility remains the couple could be a red herring.

This Is London : Hidden pursuits of MI6 man Gareth Williams’s private life

Hidden pursuits of MI6 man Gareth Williams’s private life

Justin Davenport, Crime Editor | December 22, 2010

The new details of Gareth Williams's life reveal an intensely private individual who had a life unknown to his friends, family or spy bosses.

He was a respected technician who had an occasional drink with colleagues and was an avid and competitive cyclist.

He enjoyed outdoor sports such as rock climbing as well as trips to the theatre and cinema, and his iPod showed a varied taste.

Yet today detectives revealed that the 30-year-old also had an interest in bondage websites, and visited a cabaret act featuring drag artist Jonny Woo at restaurant and theatre venue Bistrotheque in Mile End just before his death.

He went alone, but others who were at the event said Mr Williams chatted amicably with audience members.

He also held two tickets for drag shows in Vauxhall which took place after his death, and a witness has said he saw Mr Williams at Barcode, a gay bar in the area, in May.

Police revealed he had an interest in fashion, having attended two beginner's design courses at Central St Martins. Could this explain his collection of women's designer clothes and wigs worth £15,000? Intriguingly, there is no evidence that Mr Williams was gay, nor any evidence that he had ever had a girlfriend or a boyfriend.

He visited five bondage websites, including hogtie.com, artofconstriction.com and boundanna.com, browsing for between 30 minutes and an hour at a time. The sites feature women and give instruction on how to carry out bondage techniques.

But again there was no evidence that he was “obsessed” with bondage, and no pornography or bondage gear was found in his flat.

Guardian : Couple sought as police say bondage websites could hold key to spy's death

Couple sought as police say bondage websites could hold key to spy's death

• Gareth Williams's death not linked to job say detectives
• Women's designer clothes found in dead man's flat

Vikram Dodd, crime correspondent | December 22, 2010

Senior detectives believe the mystery death of the spy Gareth Williams will be solved by getting an insight into his private life after they revealed he had visited bondage websites and a drag club and had £15,000-worth of unworn designer womenswear in his wardrobe.

Williams's decomposed body was discovered in a padlocked holdall in his flat, less than a mile from MI6 headquarters in London where he was a senior analyst.

Police believe he died a week earlier, in the early hours of 16 August, and that someone else was present. For months they have struggled to answer basic questions about the death. Tests have shown no signs of a struggle or forced entry into the flat, and no sign that he was drugged.

Yesterday, Scotland Yard's detectives gave their best account of Williams's death. They revealed:

• He used his iPhone to visit websites on bondage and escape from bondage in the months before his death.

• He must have been padlocked into the red North Face holdall by someone else as it was impossible for him to have locked himself inside.

• Once padlocked in the bag, with the keys inside, he could only have survived for 30 minutes before suffocating.

• Police are desperate to talk to a couple of Mediterranean appearance who visited his block and claimed to have a key to his flat weeks before Williams's death.

• Four days before his death, he went to a club called Bistrotheque in Bethnal Green, east London, to see an act called Jonny Woo, and had tickets for two similar performances at a pub in Vauxhall, close to MI6 headquarters.

• A witness told police that Williams had been seen at a well-known gay bar in Vauxhall months before his death.

When Williams's decomposing body was found by police on 23 August, they also discovered £15,000 of unworn women's clothing, wigs and shoes in his wardrobe. The labels included Stella McCartney, Christopher Kane, and Louboutin and were in their original boxes or wrapping paper. Williams had enrolled in two fashion design courses at Central Saint Martins College, in Clerkenwell, London, in 2009 and 2010.

Speculation has been rife that Williams' highly secretive work might explain his death. He worked as an expert on codes at the government's GCHQ eavesdropping centre in Cheltenham before moving to MI6 on a secondment.

But Detective Chief Superintendent Hamish Campbell, head of Scotland Yard's homicide command, said: "This is not linked to his work – it's his private life."

He said police had been reluctant to make public details of Williams's private life, knowing it could prove distressing to his family, but were doing so now because his lifestyle could be key to solving whether his death was a sex game gone wrong, manslaughter or murder.

Police needed information from "a small subset of people" who were into alternative lifestyles and pursuits. "We want to speak to individuals who use these websites about bondage, tying up, linking into the drag world."

Police called in an expert in surviving in confined spaces, who concluded there was no way Williams could have padlocked himself into the bag. That means that someone must have been present to lock him in. The keys to the ordinary Yale padlock were found inside the holdall.

Campbell said: "Somebody must have been there to secure him in the bag on a voluntary or involuntary basis. If someone was there and it was a voluntary activity gone wrong, why not cut him free or call an ambulance?

"The alternative scenario is there is maybe something more sinister to it. We just don't know."

The dead man's body showed only two small bruises on his elbows, probably from him struggling and rubbing against the inside of the bag as he began to run out of oxygen.

Toxicology tests show no signs of drugs, although Campbell said it remained possible he had been stunned by something like a karate chop, which could have left no visible trace by the time the corpse was found. Otherwise any blow heavy enough to render Williams unconscious would have been picked up by tests.

"There is no sign of a struggle, no outward signs of anyone inflicting physical violence, no poisoning," said Campbell, who added: "The absence of violence to the body suggests he placed himself in the bag, unless he was stunned or unconscious. If that was done, it was not through drugs or super-secret injections."

The official cause of death is still inconclusive, but Campbell said: "It is most likely suffocation, but we can't be certain."

He said that Williams was a deeply private man and neither his employers nor his family knew he had enrolled into a course at a fashion college. There was no evidence that he was gay.

Police yesterday released efit images of a man and woman who visited the flats where Williams lived weeks before his death. The Mediterranean couple, who were in their 20s and dressed casually, were buzzed through the communal entrance at the flats in Alderney Street by another resident in late June or July. They said they had been given a key and were on their way to flat four, the property Williams lived in.

Williams, from Anglesey, north Wales, was last seen alive on 15 August, eight days before he was found dead.

An inquest will be held at Westminster coroner's court on 15 February.

Detectives investigating the murder of a British spy were picking over his private life today for clues that could identify his killer.

The decomposing body of codes expert Gareth Williams, 30, was found stuffed into a bag in the bath of his London Government flat.

He was days from completing a one-year secondment to the headquarters of MI6 from his job at national 'listening post' GCHQ in Cheltenham, Gloucestershire.

Further tests were taking place to determine how the cycling and fitness fanatic met his death after a post-mortem examination was inconclusive.

They could reveal if Mr Williams was strangled or asphyxiated, as well as if drugs or alcohol were present in his system.

Police believe Mr Williams's body could have lain undiscovered for up to a fortnight. Mystery still surrounds why no-one raised the alarm sooner.

It is thought he was on holiday at the time of his death. Another explanation may lie in claims that he travelled regularly to the U.S. for his work.

Detectives believe the key to the case could lie in his private life. His family said he was an extremely reserved person who kept himself very much to himself.

But investigators will be attempting to discover if the quietly spoken, mild-mannered codes and ciphers expert was leading a double life which he kept from his colleagues.

There have already been a series of lurid claims about his personal affairs while others have raised the possibility that his death was a sex game gone wrong.

Police sources said the telephone numbers of escort agencies were found on one SIM card while pornographic material had also been discovered in the flat

Detectives are examining his mobile phone and a number of Sim cards found at the address, a top-floor flat at a Georgian townhouse in Pimlico, central London.

Several clues are believed to have emerged from the analysis of telephone numbers called and received on the phone.

Parents Ian and Ellen travelled to London with his sister Ceri today from their home in Anglesey to speak to police and identify his body.

William Hughes, Mrs Williams’s cousin, said the family was deeply shocked. He said: 'The last time I saw Gareth was just a few months ago at a family party and he was fine.'

Mr Hughes said he never knew Mr Williams to bring home a girlfriend or a partner, describing him as a 'very, very private person'.

Scotland Yard detectives from the Homicide and Serious Crime unit are investigating the death in liaison with counter terrorism officers and the security services although they have not yet opened a murder inquiry.

There are no obvious signs of a robbery at the flat, believed to be one of several MI6-owned 'safe houses' in the Pimlico area.

However, security sources say they have a problem identifying what Mr Williams had so cannot be sure if anything was taken.

Experts have carried out a fingertip search of the address amid fears that top-secret work material could have gone missing.

Investigators suspect Mr Williams might have known his killer as there was no sign of forced entry at the flat in Alderney Street.

Last night it emerged that Intelligence officers were investigating whether state secrets had been stolen by Mr William's killer.

Security services fear that his murderer could have taken classified material - possibly held on a laptop or MP3 player - which could be sold on to Britain’s enemies.

A security source said: ‘Whatever the motives for this killing, there is the strong likelihood that items will have been taken and that is potentially a real problem because it may be difficult identifying exactly what he had at home.’

With much of the focus of MI6 on the terror threat posed by fanatics linked to Al Qaeda and the Taliban, one theory was that Mr Williams had been targeted because of his work.

In the flat in Alderney Street, a mobile telephone and a collection of SIM cards had been carefully laid out - in what was described as a bizarre ritualistic scene - and officers are researching each number called.

Tight security controlled the entrance to the flat, which is just a few hundred yards away from the MI6 headquarters across the Thames at Vauxhall.

Such were the precautions, it is believed, that eye scanners could have been used to gain entry.

Eileen Booth, 73, who lives opposite the flat, said detectives had come round and asked neighbours for their eye colour and height.

Mr Williams, a bachelor who had been subjected to security clearance before he was given the job, was described as a mild-mannered fitness and cycling fanatic dedicated to his work.

He was due to leave London and return early next month to his job at Cheltenham.

Finance worker Gemma Wingfield Digby, 26, who moved into the basement flat of Mr Williams’s building three weeks ago, said: ‘I saw him only once but he was such a sweet guy. All I wanted to do was give him a hug.’

Public documents reveal current and former residents of the freehold block where Mr Williams lived have links to London and Cheltenham.

One fear is that an area used by MI6 to house operatives - and where two former senior Tory politicians are neighbours - had now been compromised.

Former MI6 officer Harry Ferguson said: ‘There are lots of flats in this area owned by MI6 and their big worry will be that a terrorist group or intelligence group was involved.’

As Alderney Street remained cordoned off last night and forensic experts continued to search for clues, police were releasing little about the case.

Land Registry documents reveal that the block at number 36 is owned by a private company, New Rodina, whose details are hidden because it is registered in the British Virgin Islands and is not listed with Companies House.

The word rodina means motherland in Russian and Bulgarian. Several other residents were also linked to Cheltenham leading to suggestions the flats may have been used regularly by MI6.

The property was bought for £675,250 in 2000 with a mortgage from the Royal Bank of Scotland and has been remortgaged twice, in September 2005 and February 2006.

The documents show that the owner operated through a law firm known as Park Nelson, a firm which once occupied a rented office block in Bell Yard, off Fleet Street, but no longer appears to exist.

One Frenchman who lived at the flat between 2005 and 2006 is an expert in global satellite positioning, radio communications and high sensitivity antennae.

THE SPY THEY CALLED THE QUIET MAN: MATHS GENIUS, LONER AND CYCLING FANATIC AT THE CENTRE OF MYSTERY

Few who crossed Gareth Williams’s path would have been surprised to learn that he was a spy.

A mild-mannered loner, who preferred cycling on gruelling lone runs to the pub or clubs, acquaintances knew him as ‘the quiet man’.

His landlady for a decade, Jenny Elliott, yesterday recalled how the 31-year-old bachelor lived without a TV in the annexe of her home, often hearing him working alone on the tapes she knew were part of his work.

‘There was never noise, never a problem,’ she said. ‘He was the perfect person to have in your home... a genuinely nice, decent man.’

Retired office worker Mrs Elliott, 71, and her husband Brian came to know Mr Williams well during the ten years he spent with them at their £500,000 home in the Prestbury area of Cheltenham, while he worked for GCHQ, the government’s listening centre.

‘It’s a real tragedy,’ she said. ‘Gareth was a really nice guy who was polite and mild-mannered and wouldn’t hurt a fly.

‘When someone has lived with you for ten years you get to know them really well, and Gareth almost became a part of the family.

‘Gareth was a very likeable person but didn’t really have any friends as such. He was a cycling fanatic and was forever off on some bike ride or another but never really had friends round.

'He was an extremely intelligent person but would not talk about his job as it was a secret, on account of working for GCHQ. All he told me was it was something to do with codes.’

The last time Mrs Elliott spoke to Mr Williams flat was two weeks ago, when he called to confirm when he would be returning to Cheltenham from London.

He was a keen cyclist with the Cheltenham and County Club and took part in uphill races - coming eighth in a recent event.

Mrs Elliott said she did not remember him ever bringing a girlfriend back to the self-contained flat, comprising a bathroom, bedroom and kitchen, above her garage.

’That’s not to say he didn’t meet girls. But if he did, he certainly didn’t talk about them to me.

‘Gareth occasionally said he was meeting some of the guys from work for a quiet drink but he wouldn’t tell me who they were or where they were going and I never pried.

'He never had a television and I never heard music coming from the flat. He was the perfect tenant and I doubt I’ll be able to find one as good as him again.’

Mr Williams, a Welsh speaker, was raised in Holyhead on Anglesey by his father Ian, who worked at the nuclear power plant, and mother Ellen, together with sister Ceri.

Friends recall how it was his father who led Gareth to a love of cycling and together they were a frequent sight - even recently - pounding the roads of Anglesey.

According to his uncle William Hughes, it was always apparent that Gareth was an outstandingly bright boy.

‘The family knew this from a very, very young age. He was a very clever lad. When he was at secondary school he would go to university one day a week.’

According Mr Hughes, Gareth graduated at the age of only 19 from Bangor University and went on to Cambridge to continue his studies.

‘He was quiet, unassuming. When he came home on his weekends and holidays he’d be on his bicycle riding around the lanes of Anglesey.

‘He worked for GCHQ for many years. We knew he was working in London, but he’d never talk about his work and the family knew not to ask really. We didn’t know what he was doing. He never spoke about it.’

Mr Hughes added that to learn of the murder was a terrible shock.

‘I got a phone call... I couldn’t believe that such a thing had happened.’

John Barnes, who once worked with Gareth Williams’s father and who regularly cycled with the two men, said: ‘Gareth was brilliant at maths - a genius.’

Mr Williams’s parents were abroad on holiday when their son’s death was discovered and were said to be staying last night in London. Scotland

Yard detectives were at the family home in Holyhead, where they were speaking with the dead man’s sister, Ceri Subbe, who lives with her doctor husband, Christian. #

FOR YOUR EYES ONLY: THE INTRIGUING TRUTH ABOUT LIFE AS A 21st CENTURY SPOOK

By MICHAEL BURLEIGH

Whether he was killed by Islamic extremists, Russian gangsters or someone altogether closer to him, MI6 operative Dr Gareth Williams died a spook's death.

Murdered in his Pimlico penthouse - which is owned by a Russian-named, British Virgin Islands-registered company - his body was found in the bathroom, in a sports bag.

Nearby, a mobile phone and numerous SIM cards had been laid out on a table. As murders go, it is the stuff of Bond films.

Williams usually worked in Cheltenham, inside the vast doughnut-shaped complex that is the Government's top secret communications monitoring agency, GCHQ - and was reportedly on secondment to MI6.

Indeed, 'Ceaucescu Towers', as MI6's brutally modernist Vauxhall Cross HQ is known, is just across the River Thames from his apartment, overshadowing a huge bus terminal, and the gay clubs and saunas of 'VoHo' - the area's red light district.

But are GCHQ and MI6 operatives such as Williams really James Bond figures? And what exactly do they do?

Gone are the days when agents were recruited after a discreet word from their Oxbridge tutor. In the 21st century, spooks are recruited like anyone else. Posts are publicly advertised, and hopefuls must first sit the kind of psychometric test - devised to reveal their powers of analysis and observation - that many blue chip companies now employ.

Nor are the successful candidates guaranteed an exotic life of high jinks and murky subterfuge. While television series such as Spooks - which is about the domestic intelligence service, MI5 - have glamourised life in Britain's secret services and have certainly proved a useful recruitment tool, the daily reality is rather less dramatic.

Many of the workers at GCHQ, for example, spend their days - and often nights - trawling through billions of emails, text messages and telephone calls, looking out for the one communication that might prove crucial.

They seek to glean intelligence on a wide range of targets, including terrorists, organised criminals and hostile foreign governments. They also seek to foil the growing threat of cyber attacks launched against Britain's banking system.

In 1998 they played a major role in locating the fugitive murderer Kenneth Noye - after he fled to southern Spain - by tracking his mobile phone.

During the Seventies, Eighties and Nineties, GCHQ waged a sophisticated electronic war against the IRA. It used electronic signals to prematurely detonate radio-controlled bombs, or listened in on telephone conversations between terrorists, looking out for such phrases as 'Are you coming out for a drink then?' - meaning an attack was imminent - or 'the bricks are in the wall' - a bomb is in place.

Much of this expertise will now have been re-directed, along with GCHQ manpower, to pick up fanatical Islamists using coded language about the imminence of a 'big wedding', a favourite code for a bomb attack.

But some of their operations seem downright bizarre. After the entire electricity grid in Auckland went down in the late 1990s, for example, GCHQ helped the New Zealand authorities trace the cyber-attack back to a group named the 'Anti-Christ Doom Squad', which had managed this feat from a laptop in an Amsterdam drug café.

GCHQ also eavesdropped on UN diplomats from six (friendly) nations crucial to the Security Council's second resolution on the permissibility of the Iraq War. Some, including Mexico, are still demanding an official apology from the UK.

Holding a doctorate in maths, Williams would have been wellqualified to work in a service which uses extremely complicated decryption methods to access sensitive - and heavily protected - information.

No wonder one former landlady said that the only noise she heard from Williams's otherwise hushed flat was the whirr of audio tapes.

Much of the work of GCHQ overlaps with that of MI6, who deal with real people rather than data pulsing through the ether. But most of MI6's agents are also worlds apart from the fictional figure of James Bond.

The majority of MI6 agents work in office jobs, inside the Vauxhall Cross complex. Here, they also sift through masses of data, about 90 per cent of which is 'open source'.

That means it is available to you or I, in newspapers or via the internet. They certainly bring acute analytical skills to the table, but several former ministers have openly questioned the value of what they yield.

Indeed, only 150 or so MI6 personnel are actually stationed abroad as secret agents. They are usually 'camouflaged' as counsellor, first secretary or protocol officer on the official lists of serving British diplomats working in key embassies.

Their main job is to recruit foreign agents, often people with inside knowledge on defence or commercial matters - the links between the security services and British business run deep - that might give an edge to British interests.

Some of these contacts will volunteer their services; others will have to be blackmailed or coerced into co-operating.

These operatives will spend much of their time hanging around the sort of places where lonely businessmen, civil servants, politicians or journalists congregate.

In fact, it used to be said that MI6's real work began after 6pm, when the interminable round of diplomatic cocktail parties started.

Being the life and soul of the party, rather than a gormless wallflower, was essential to the job, which may explain why so many men like Guy Burgess or Donald Maclean - the notorious KGB double agents - became hopeless drunks.

It was a tradition that continued with rogue MI5 officer Michael Bettany. On one occasion, when caught the worse for wear travelling on a train without a ticket, he shouted: 'You can't arrest me, I'm a spy.' Indeed he was, selling British secrets to the Russians, for which he was jailed in 1984.

Of course, nowadays, MI6's contemporary Al Qaeda and Taliban opponents are not to be found sipping gin at embassy receptions.

And so a handful of MI6 agents will be getting down and dirty, not just with their opposite numbers in the Middle East, but with the local people who inhabit dusty mountain encampments.

Chief among their tasks will be monitoring British subjects who claim to be in Afghanistan or Pakistan attending family weddings when they are really planning the next London Tube bombing in a terrorist training camp.

These agents will also be directing covert strikes on Taliban leaders, while simultaneously seeking to peel off the more amenable or corruptible ones to join the Afghan government.

This is extremely dangerous work, requiring a clear sense of purpose and nerves of steel. But they are also the minority.

Regardless of how Dr Williams died, and it may be that he was killed by someone close to him for reasons that were obscurely personal, he was part of a highly secretive, but often surprisingly mundane, culture.

And that, presumably, is why his mysterious death is the exception, rather than the rule.

Guardian : Who was Gareth Williams?

Who was Gareth Williams?

When the bagged body of an MI6 agent was found in a bathtub, speculation went into overdrive. Was it suicide? Murder? A professional hit, or a sexual game gone wrong?

Cathy Scott-Clark and Adrian Levy | November 20, 2010

Three months after his body was found in a holdall in the bath of his Pimlico flat, police still seem no closer to finding out what happened to Gareth Williams.

On Tuesday 24 August, a storm was brewing off the North Wales coast. As gusts reached 50mph in the village of Valley, on Anglesey, two sodden police officers stood at a front door on a close of modern bungalows above the beach. They knocked and knocked. Eventually someone ran out into the rain to tell them that Ellen and Ian Williams were away on holiday in the US. While detectives tried to locate the Williams abroad, someone found Ellen's father, John Hughes, who lived around the corner and broke the news: his 31-year-old grandson Gareth, a boy who had always been fit and healthy, was dead. Grandpa John was so distraught that he tripped, cut his head and had to be taken to hospital.

Then Gareth's uncle, William Hughes, who lived on a farm in nearby Trefor village, got the call. "Gareth couldn't be dead? Surely not?" Uncle William sat numbly with Gareth's 86-year-old great aunt before their open fire, staring at the porcelain figures on the mantelpiece. Gareth had been an exceptional boy, selected to work as some kind of analyst for GCHQ, the government's secret listening station in Cheltenham, but the family never talked about it. And neither did Gareth. He'd been home just three weeks earlier, recalled Hughes, cycling the lanes on his race bike before the whole family had got together. But his life was "now being lived a long way from the family in Anglesey," Hughes said, "so some things we couldn't know."

On 25 August, Ian and Ellen Williams touched down at Manchester airport and were met by police, who officially broke the news that two days earlier in London, a man believed to be their son had been found dead. The body had been found padlocked inside a sports bag in the flat where Gareth was staying. It could have been there for up to a fortnight. As they were escorted to the capital, to join their daughter Ceri, there were news reports everywhere: "British spy murdered." Apparently he had been "stabbed to death". According to stories, Gareth was a brain-box, a techie who "worked with codes", as far as they knew. Was he also a spy, they wondered?

For Ellen and Ian, Gareth's death was a horror story that "destroyed" them. For the rest of the world, it was a rare glimpse into the clandestine world of espionage. His death was compared to that of Georgi Markov, the Bulgarian dissident killed by a poison-tipped umbrella in London 32 years before, and the 2006 murder of Russian dissident Alexander Litvinenko. Cold war details increased public fervour. The building in which the body was found was owned by a private company, registered offshore, called New Rodina. Rodina was Russian for "motherland". Did real spies read John Le Carré too?

In the midst of lurid speculation, Ian and Ellen Williams reached London. In normal circumstances, they would be required to make a physical identification. However, given the degree of decomposition, police would rely on family photos. Was Gareth murdered, his distraught family asked. Despite launching a major investigation – Operation Finlayson – Scotland Yard were finding it a hard question to answer. One major problem facing investigators was the length of time that the body had lain undiscovered. Another was that they were being blocked by the security services from probing too deeply into Williams's life. Detectives had no idea what Gareth Williams really did or who he was, and had been unable as yet to find anyone close to him. They needed the family's help.

Gareth's sister Ceri, a physiotherapist, and her husband Dr Chris Subbe, a senior registrar at Wrexham Maelor Hospital, told police they had seen Gareth in June, when he had taken them for tea at the Ritz in London to celebrate their second wedding anniversary. He'd been in the capital for more than six months, but couldn't say what he was doing.

The three spent that afternoon "laughing and joking", and afterwards continued to talk frequently by phone. Ceri last spoke to her brother on 11 August, after he returned from a short trip to the US. He now intended to "tidy things up", before returning to GCHQ in Cheltenham on 3 September.

Ceri's dates matched what police learned from Gareth's former landlady, Jenny Elliot, who had rented him a room in her house near Cheltenham for the 10 years he had worked for GCHQ, before transferring to London last year. Gareth had called her in August, asking if he could return. "Like we were going to say no," Elliot says. "He was about the best lodger you could ever have. I mean, you never heard a word from him. He had no TV, record player, or anything."

Ceri had called her brother again about a week later. No answer. She tried repeatedly, becoming worried. Gareth was like a Swiss watch. Now she contacted the police; the security services were already concerned, as Gareth had failed to show for work. On 23 August, at 6.30pm, a uniformed officer was sent to Williams's top-floor flat in a Georgian townhouse in Alderney Street, Pimlico. It was only a few hundred yards from the MI6 headquarters at Vauxhall, and was used by the Secret Intelligence Service as a safe house. A lettings agent who held a spare key showed the policeman in. He was asked to wait downstairs as the officer went up and entered the curtained rooms. The place was "spotless": two iPhones, some sim cards and an Apple notebook sat on a table. Then he entered the bathroom, and found a holdall in the bathtub. Red liquid seeped from it. Inside was a body, in such a contorted position that he thought its "legs and arms had been cut off". Radioing for assistance, the policeman noted that there were no signs a struggle. This was not a robbery or home invasion. It was a "neat job", a euphemism for a professional kill.

Given his clearances and access to classified material, Williams's death triggered alarm across Whitehall. MI5 agents swept through the Alderney Street flat, followed by detectives from the Homicide and Serious Crime Command, assisted by SO15, Scotland Yard's Counter Terrorism Command. Alderney Street was cordoned off as Home Office scientists began processing the scene. Once the spooks had departed, it was down to the murder squad to study the evidence. So far, they had a body in an "advanced state of decay". There was no weapon and no sign of forced entry or a struggle.

Concentrating on the holdall and its contents, detectives established that Williams had not been stabbed, shot or hacked to pieces. On August 25, Home Office pathologist Dr Ben Swift carried out a post-mortem that, together with the first batch of toxicological tests, came back "inconclusive". "If we don't know what to look for, and are not guided by what we see or smell on the body, we cannot find it," says a forensic scientist who worked on the Litvinenko case. "We do 50 obvious poisons. Fifty rare. We can do the isotopes. Litvinenko alerted us to that. But in the absence of a specific direction, the possibilities are as limitless as a killer's imagination… and we cannot test for that."

Detectives set out their theories. One reading of the crime scene pointed to a forensically aware hit man. Slender 5ft 7in Gareth had been stuffed inside the near-airtight red North Face sports bag and placed in the bath, containing any spillage and minimising odours, too. The heating was on, increasing the rate of decomposition, which significantly lessened the chances of retrieving evidence from the corpse.

Or perhaps the body in the bag was evidence of a stage-managed "personal event", masterminded by a controlling individual. Was this a suicide (with Williams acting on his own)? Or a sadistic or masochistic sexual act gone wrong (with Williams engaging in some kind of auto-erotic asphyxiation?). "If you can imagine it, then we are investigating it," a detective said in late August. But what would shape police inquiries was the dawning realisation that Gareth Williams had not been alone.

Returning to the holdall, studying the zips and lock, police became certain that he could not have locked himself inside. And there was further proof that someone else must have been in the flat with him: his front door had been locked from the outside.

Criminal psychologists studied the case. One, who spoke anonymously, thought his death might have been a masochistic ritual that had gone wrong: "For a retentive individual with an ever-green mind like Gareth Williams, always on duty and in control, the bag could have been a furtive release."

The Williams family was adamant that the Gareth they knew would not have behaved this way. And, for now, the family was all the police had, since they had found no close friends or lovers. Another pressing problem with their theories was that detectives had failed to turn up any other suspects or accomplices.

Police, pathologists and forensic investigators agreed on one thing only. They would have to focus on the 12 days between the last call Gareth made to Ceri and the discovery of his body on 23 August. Pulling mobile phone records and credit card transactions, scouring hours of CCTV footage, the Operation Finlayson team dug deep, as ever more lurid stories circulated.

"Murdered MI6 worker Gareth Williams was a secret transvestite who may have been killed by a gay lover, detectives said yesterday… Cops found women's clothing that would fit him at his Pimlico flat in central London." The Sun ran with this version of events, while other newspapers, quoting similar unnamed sources, reported that cocaine had been found, a cache of gay pornography, a small armoury of S&M paraphernalia. Williams was also said to have frequently paid for male escorts.

Senior detectives angrily rebutted the stories. Uncle William in Anglesey thought they read like a concerted smear, and wondered why anyone would want to destroy Gareth's reputation after he was dead.

Like most well-constructed character assassinations, however, this one was founded on a grain of fact that made it that much harder to quash. Detectives had been quietly investigating whether Gareth Williams was gay. They had canvassed witnesses in the Vauxhall Cross village of gay clubs and bars, a short walk from Alderney Street. They had also studied Williams's computers and reading matter, his journals, magazines and computer cache. Despite outright denials from his family, detectives were privately certain that Gareth was gay, although they had been unable to find trace of any sexual encounters. They had also come to believe that his sexual orientation was not central to the inquiry (although his sexual preferences might be). There was no evidence of Williams paying for escorts, buying S&M equipment, using porn or drugs of any kind. "This man didn't really even drink," one frustrated detective said.

The police felt they were being hurried along by other parties, keen for the scandal to go away. "Someone, somewhere, who has access to case material, is saying, 'He's queer and asked for it', rather than waiting for the outcome of the case," one veteran detective said.

In North Wales, the family lit their fires, closed their curtains and privately pondered if anyone had ever understood the real Gareth.

At Ysgol Gynradd Morswyn, Gareth's primary school, a short hop between Valley and Holyhead, head teacher Islwyn Williams remembers him as an exceptional pupil. At five, Gareth made a beeline for the school computer and never left it. While most of his classmates were still playing with Lego, Gareth had a GCSE in maths. At the age of 10, he went to secondary school, gaining A grades in A-level maths and computer science at 13. The school contacted Bangor University, which accepted him as a part-time student on a maths degree course. "He was the best logician… with the fastest brain I have ever met," said Geraint Williams, his maths teacher.

Fellow pupils remember Gareth as a loner. Dylan Parry, 34, thought him "isolated" by his intellect. His abilities shut him off from everyone else. He was naive. Parry believed someone "could easily take advantage of him". He recalled Gareth travelling by train each week to university, while still living at home with Ian and Ellen. Too clever for school. Too young for university.

The family downplay his isolation. They point to their closeness and his sporting prowess. By the time he was 17, Gareth had followed his father into competitive cycling. Keith Thompson, of Holyhead Cycling Club, with whom Ian and Gareth rode, says: "He was a really lovely young man, but wasn't a great conversationalist. Gareth wasn't the sort to go to the pub after a race."

In 1997, aged 18, Gareth left home to begin a PhD at Manchester University, acquiring an advanced level of learning that sat uneasily with his elementary life skills, although his academic mentor, professor Terry Hewitt, believed he could take it: "He was very private and worked well on his own. He was certainly not a 'geek' even if he was reserved." His dissertation focused on computer games. They had always been a private passion, with him achieving an online reputation as unbeatable. Three years on, aged 21, Gareth was approached by the British security services, who the university believes had spotted his precocious online gaming abilities. Hewitt recalled: "In 2000, Gareth came into my office and said, 'I'm going to GCHQ'. He had to tell me, as I was his referee for his vetting." Gareth left Manchester and Anglesey behind to sign the Official Secrets Act.

Williams began an advanced maths course at St Catharine's College, Cambridge, but withdrew the following year, torn between academia and the demands of his new employer. At GCHQ, he was seen as stable, reliable and potentially brilliant, according to a contractor who worked there at the time. Speaking on condition of anonymity, he recalled that GCHQ was a world in which Gareth fitted, working alone, or in small teams, waist-deep in mathematical problems, challenged by cutting-edge technology and real-time problems. Possibly for the first time, he was part of a community of similarly focused individuals who were taken on for their discretion as well as for their brains, intercepting, monitoring and analysing email and telephone calls from around the world. He did feel the pressure, constantly, according to the contractor, who noted that at GCHQ many technicians were as clever or cleverer than Williams.

Work became his life. There was little time for much outside it, something evidenced by how he chose to live, renting a modest room in the Prestbury area of the town. Inside was a single, child-sized bed, a small chest of drawers, three upright wooden chairs and a gas heater – all furnished by Jenny Elliot. Over the decade he spent there, Williams introduced no luxuries, accumulated no clutter. He brought no one back. He rarely even went out after work, excepting an occasional "drink with colleagues". He worked late into the night and rose early. There was something oppressively austere about him, those colleagues thought, something they used to call his "GDR sensibility". So serious and quiet was he that when he did become animated, he "alarmed people with his unusual laugh".

Due to the nature of his work, it is hard for those who met Gareth to describe what he did, and those who talked to us did so having already left GCHQ. But all agreed that, although very capable, Williams was "a middle-ranking" technician "asserting himself in a number of sensitive areas, any one of which could theoretically have brought him into contact with enemies of our state". While GCHQ gathers intelligence from Europe, Africa and Russia, its partners in the US National Security Agency (NSA) also had access to British and European signals traffic at Menwith Hill, a top-secret RAF base near Harrogate, in Yorkshire.

When Williams arrived at Menwith, shortly after the invasion of Iraq in March 2003, GCHQ and the NSA were increasingly focused on the threat of Islamist violence at home and abroad. "Between the UK and the US, we were deluged by the chatter from radicals here and over the Atlantic as they talked on landlines, satellite or mobile phones – with contacts in hot countries like Pakistan and Afghanistan, as well as with Saudi, and hubs like Dubai," one former GCHQ security consultant said. "A group around Williams worked on software to assemble, search and analyse the data, drawing out patterns and meanings."

Williams's elevation within GCHQ came with the "Liquid Bomb" plot, where a group of British radicals of Asian origin were found to be planning to detonate home-made explosives on board seven flights to major north American cities. Intercepting emails and phone calls between these plotters and their contacts abroad, Williams flew between the UK and the US, working at Fort Meade (the NSA HQ, in Baltimore).

Williams was brought into close proximity to US intelligence, Islamic radicals and Middle Eastern agents. He would rub shoulders with the Russians, too, according to a foreign intelligence analyst based in the UK, who described how technology and software honed by GCHQ was deployed in tracking a Moscow-backed sleeper cell to which Britain had been alerted as early as 2003. The case blew up in June 2010 when 10 people were arrested in the US and accused of being part of an espionage ring. One of them, a glamorous 28-year-old called Anna Chapman, had lived for five years in the UK. According to the former GCHQ contractor, "Williams had been obsessed by the case, its methodology and characters."

He was now on secondment to MI6, with its focus on foreign targets and intelligence-gathering, becoming more of a spy than a desk-bound technician, although Williams would shortly be called back to GCHQ to work on a new and ambitious project.

He had been liaising again with counterparts at the NSA, who were part of an effort to create an American cyber defence policy, to prevent the siphoning off of secret or commercially sensitive data or a military style assault on defence or civil systems. Its importance was alluded to last month in a speech by home secretary Theresa May, in which she identified cyber crime as among the pre-eminent future threats facing the UK. A cyber crimes specialist who knew Williams revealed that at the time of his death he was researching British vulnerability to Russian, Turkish and Chinese gangs: "He was already on top of it."

Rogue individuals and nation states, Islamist terror groups and radical loners, extortionists and organised criminals – these were just some of those Williams had observed, investigated, disrupted and provoked. Any one of them was capable of reciprocating, lethally.

Back at the Yard, Operation Finlayson detectives were looking at a vast range of potential threats, but still had few clues, no accomplices or even a plausible denouement for a man whose personal and professional inclinations were to camouflage everything he did.

By September, an exhaustive trawl had come up with some CCTV footage. In the frames released to the public, Gareth Williams saunters by Holland Park tube station in west London at 3pm on 14 August, three days after he had last spoken to his sister.

Staff at the nearby Valerie's Patisserie said that in the week before, a man fitting Gareth's description had spent several hours in the cafe on consecutive days, sitting at the rear with a laptop, receiving occasional visitors. One security source said that he believed Williams was "working" in west London – monitoring one of the many foreign embassies in the area – just as he had been "working" while on his recent "holiday" to the US.

Police released footage of Williams on 15 August, too. At 2pm, he was filmed at a cash machine, visiting Harrods, walking at 2.30pm via Hans Crescent in Knightsbridge towards Sloane Street. Soon after he vanished.

By the end of September, after a second barrage of toxicology tests proved inconclusive, Gareth Williams's body was released and laid to rest in North Wales. On 26 September, the extended Williams clan gathered outside the Bethel chapel in Holyhead to bid farewell. Given the florid rumours that had circulated around his death, they were surprised by the appearance there of Sir John Sawers, head of MI6. Williams had been with his service for less than a year, yet Sawyers told reporters, "I wanted to be here today as the only public face of the Secret Intelligence Service. My deepest sympathies go to the family. Gareth was a hugely talented person, and he was very modest and generous as well. He did really valuable work with us in the cause of national security."

What a difference 30 days make. After an investigation that had failed to turn up the smallest vice, Williams was no longer lampooned but celebrated as a very British spy: modest, capable and known well by no one.

As they buried Gareth, Dr Chris Subbe, speaking for his wife Ceri and the family, recalled how they had laughed and chatted with him at the Ritz, celebrating their marriage and his brilliant career. "The world was ours for the taking," he said. "Yet here I am three months later to the day, trying to describe your rich life with my poor words."

Independent : David Randall: Baffling death ...

David Randall: Baffling death ...

October 31, 2010

Surprisingly little attention – given the international hoo-ha his death caused – has been given to Thursday's results of toxicology tests on the body of MI6 mathematician and code expert Gareth Williams. He was found, remember, naked, in a kneeling position, inside a large sports holdall which had been padlocked. The tests showed no trace of poison, alcohol, or drugs in his body, which knocked on the head the idea that Mr Williams had been sedated, bagged up, and left to die.

Other theories, however, continue to flourish, among them the persistent one that Mr Williams was afflicted with a sexual kink only satisfied by severe confinement. The Sun reports that he had recently visited websites on claustrophobia and sadomasochism, allowing them to headline their story: "Bag spook died in 'Houdini' game". Similar reports have been denied in the past, and all police will say is that they continue to seek a couple who were let into Mr Williams's flat shortly before the assumed time of his death.

Toronto Sun : MI6 spy died in sex game gone wrong

MI6 spy died in sex game gone wrong

By QMI Agency | October 30, 2010

Police now believe that Gareth Williams, the former codebreaker for Britain's Secret Intelligence Service MI6 whose body was found naked in a padlocked gym bag in his west London flat, died accidentally from the lack of oxygen during a sex game gone wrong.

British tabloid The Sun reports that police say the 31-year-old man got sexual pleasure from being confined in small places and agreed to be locked in a 32-inch long North Face sports bag.

Police believe Williams died quickly from the heat and lack of air inside the bag while the person who locked him inside was out of the room. When the person realized Williams suffocated to death, he or she put the key inside the bag and moved it to the bath tub where police found the body on Aug. 23.

Toxicology reports came back clean and police have ruled out foul play but are looking for the person who locked Williams inside the bag as well as a couple that visited his apartment a month before his death.

The former codebreaker's computers showed that he visited websites on claustrophilia as well as bondage and sado-masochism.

Daily Mail : Clues point to sex game: MI6 spy Gareth Williams had 'no traces of foreign substances' in his body which was found zipped in a sportsbag

Clues point to sex game: MI6 spy Gareth Williams had 'no traces of foreign substances' in his body which was found zipped in a sportsbag

By Daily Mail Reporter | October 29, 2010

The MI6 spy found dead in a sports bag was not poisoned or under the influence of alcohol at the time of his death, tests have revealed.

After investigating all other avenues, detectives now believe it was a sadomasochistic sex game which led to Gareth Williams' death.

Toxicology tests ruled out the possibility of him being drugged or injected with any lethal toxin.

The codebreaker’s naked body was found locked in a sports bag in his empty bath.

Tests on his body, which have taken two months to complete, have failed to find any foreign substances – or alcohol – or give any indication as to how he died.

Police are now focused on finding a couple known to have been with the 31-year-old in the weeks before his death.

The Mediterranean couple, who are understood to have had a set of keys to the flat, are thought to be key to the investigation.

The man and woman, in their thirties, were known to Mr Williams and were seen entering the flat owned by the intelligence services in late June or early July. But, despite repeated appeals, they have failed to come forward.

Detectives are convinced that the cipher expert could not have died alone.

One possible explanation being investigated by detectives is that Mr Williams was locked in the bag by someone else and left in the bath as part of the bizarre sex game. It is thought that when the person returned to release him they found him dead and fled.

Police are certain he was alive when he was padlocked into the large holdall by, which led to him suffocating. There were no injuries on his body to suggest a struggle.

Inquiries continue into his private life, which officers remain convinced will be the key to solving the case.

There has been months of speculation about the death of the spy, who had been working for the Secret Intelligence Service on secondment from GCHQ in Cheltenham.

The inconclusive toxicology results will only serve to deepen the intrigue surrounding the case.

Mr Williams’ decomposing body was found inside a zipped and padlocked North Face bag in his flat on August 23.

Initially it was thought the cycling enthusiast had been murdered, but the case remains officially classified as ‘suspicious and unexplained’.

Police have discounted suggestions that Mr Williams committed suicide alone. The Mail has learnt that the outer door to his flat in Pimlico, Central London, had apparently been locked from the outside when police arrived on the scene.

Detectives have found no evidence to support claims that Mr Williams was a cross-dresser, that bondage equipment was found at his home, that a laptop was missing from the flat, or that he had reported to spy bosses that he was being followed.

Nor, as was claimed in one report, was any suspicious liquid found next to his body in the sports bag.

Police have also dismissed allegations of irregularities in his finances and there is no evidence that Mr Williams had committed any criminal acts.

The spy was last seen eight days before his body was found. CCTV showed him shopping at Harrods and at Holland Park tube station.

Colleagues later raised the alarm after he had not been seen for days.

Officers found no sign of any forced entry to the property or a disturbance inside. Westminster Coroner Dr Paul Knapman is due to review the case in private next Wednesday, after opening an inquest last month.

Yesterday a Metropolitan Police spokesman said: ‘Results from comprehensive further toxicology tests carried out in relation to the death of Gareth Williams have come back negative, showing no trace of any drugs, alcohol, poisons or any other substances that would indicate cause of death.

‘There are no plans to carry out any further tests of this type, but enquiries continue to try and establish a formal cause of death.

‘Mr Williams’ death remains suspicious and unexplained and enquiries into the circumstances continue.’

Evening Standard : Spy found dead in bag may have had a fetish for confined spaces

Spy found dead in bag may have had a fetish for confined spaces

Justin Davenport, Crime Editor | October 29, 2010

MI6 spy Gareth Williams may have died as a result of a bizarre sexual addiction to being enclosed in confined spaces, it emerged today.

Detectives are investigating whether the code-breaker, whose naked body was found inside a zipped and locked holdall, was a fan of so-called “claustrophilia”.

Mr Williams, 31, is thought to have died accidentally from a lack of oxygen after he agreed to be locked inside the red 32-inch long North Face bag by another person. One possibility is that the sex game went tragically wrong and the second person returned to find Mr Williams had died. The man — or woman — then fled the Pimlico flat, not leaving any forensic clues.

Police are now concentrating on Mr Williams's private life which detectives are convinced holds the answer to how he died. An examination of the spy's two laptops found in the flat showed he visited websites on claustrophilia, a desire to be confined in closed spaces.

There were also said to be links on one computer to a bondage and sado-masochistic website.

The development emerged as Scotland Yard announced that tests on the MI6 employee's body revealed no traces of any alcohol, drugs or poisons that may have caused his death.

Mr Williams's decomposing body was found in the padlocked holdall in the bath of his flat on August 23. The spy was last seen eight days before his body was found and detectives believe he may have lain undiscovered for several days. CCTV showed him shopping at Harrods and at Holland Park Tube station. There were no injuries to his body and nothing in the flat that suggested a struggle or forced entry.

A post-mortem examination has been unable to find a cause of death but it is possible he died from a combination of suffocation or dehydration, which is difficult to identify.

Police do not believe that he was able to lock himself into the North Face bag on his own and suspect at least one other person was inside the flat at the time.

They are still trying to trace a couple, both of Mediterranean appearance and aged between 20 and 30, who had paid a visit to Mr Williams's flat about a month before he was found dead. Despite repeated appeals they have not come forward.

A colourful wig and women's make-up were also found inside the flat, but detectives can find no evidence that Mr Williams was a cross dresser. Sources say he was an intensely private individual who appears to have gone to great lengths to hide details of his private life.

Mr Williams, a keen competitive cyclist, was on a year's secondment to MI6 from GCHQ, the Government's electronic eavesdropping agency in Cheltenham.

Coroner Dr Paul Knapman is due to review the case in private next Wednesday.

A Metropolitan Police spokesman said: “Results from comprehensive further toxicology tests carried out in relation to the death of Gareth Williams have come back negative, showing no trace of any drugs, alcohol, poisons or any other substances that would indicate cause of death.

“There are no plans to carry out any further tests of this type, but inquiries continue to try to establish a formal cause of death. Mr Williams's death remains suspicious and unexplained and enquiries into the circumstances continue.”

British spook Gareth Williams died in Houdini sex game, say police

From: NewsCore | October 29, 2010

A BRITISH who was found naked and zipped up in a red duffel bag in the bathtub of his London apartment suffocated after a bizarre sex game went wrong.

Police believe 30-year-old math Gareth Williams genius died accidentally from a lack of oxygen after he agreed to be locked in the 32-inch-long sports bag by another person, The Sun newspaper reported.

Sources said the MI6 agent was a fan of claustrophilia - in which people get sexual pleasure from confined spaces.

Police have suggested that the person who zipped up the bag discovered Williams dead and fled the apartment. They have ruled out foul play but are still trying to trace the other person.

An examination of his two laptops showed Williams visited websites on claustrophilia.

He also had links to a bondage and a sadomasochism website. Two wigs and women's makeup were reportedly found in the victim's apartment.

Williams was zipped into a large North Face bag and a padlock was snapped shut through two eyeholes in the handles - but the key was found inside.

Investigators hoped toxicology tests would shed light on Williams' cause of death, but according to a statement released on Thursday: "The Metropolitan Police Service can confirm that results from comprehensive further toxicology tests carried out in relation to the death of Gareth Williams have come back negative, showing no trace of any drugs, alcohol [or] poisons ... Williams' death remains suspicious and unexplained, and inquiries into the circumstances continue."

There were no signs of forced entry or traces of blood at the scene.

Police again appealed on Thursday for information about a man and a woman seen at Williams’ apartment in late July. Both were described as of Mediterranean appearance and aged between 20 and 30 years old.

Williams, who worked at the Government Communications Headquarters fighting cyber warfare, was living in London on a temporary assignment for MI6.

Express : SPY’S FATAL ‘HOUDINI SEX GAME’

SPY’S FATAL ‘HOUDINI SEX GAME’

Gareth Williams suffocated himself accidentally during a sex game, police believe

By John Twomey | October 29, 2010

SPY Gareth Williams suffocated himself accidentally during a sex game which indulged his fetish for being locked in confined spaces, police believe.

The MI6 officer took his “Houdini games” too far when he was locked in a large sports bag at his flat.

Williams, 31, stripped naked and climbed into the sports bag in his bath, armed with a padlock key.

Scotland Yard detectives believe he asked someone to snap the padlock shut on the bag’s zip and leave him to find his own way out. But the lock was on the outside of the bag and he could not reach it. With little oxygen in the sports bag, he soon passed out and suffocated.

Officers are still looking for a mystery couple seen at his flat who could explain how the padlock on the bag was snapped shut.

It is still not clear whether anyone was in the bathroom when the spy started struggling for air. Williams may have told the person to leave the flat after locking him in the bag to add to the asphyxiation “sensation” and the feeling that he was dicing with death.

The codebreaker was found dead in the bath at his flat in Pimlico, central London, on August 23. He had been there for up to eight days.

Police checks on his laptop computers uncovered links to weird websites, including one called Torture Garden which deals with fetishes like claustrophilia.

OFFICIAL: SPY IN BAG GARETH WILLIAMS DIED DURING KINKY SEX GAME

By Paul Robins | October 29, 2010

THE spy found dead inside a padlocked sports bag suffocated during a sex game, police claimed yesterday.

New evidence revealed spook Gareth Williams got his kicks from being trapped in confined spaces, a fetish known as claustrophilia.

But detectives claim things went wrong when he could not get out.

The brilliant codebreaker’s body lay undiscovered for two weeks in the bathtub of his London flat.

But police believe they have solved the mystery after finding links to weird torture websites on the M16 officer’s laptops.

One called Torture Garden gives advice and tips on bizarre fetishes like claustrophilia.

Its believed Gareth, 31, stripped naked before asking someone to snap a padlock shut on the bag’s zip and leave him to find his own way out.

He was stuck in a semi-foetal position and was soon left struggling to fill his lungs with air.

The spy had taken the padlock key into the bag as his “life line” but because the padlock was on the outside he was unable to reach it.

With little oxygen in the bag, he soon passed out and suffocated. Police are convinced the spook would not have been able to lock it from the inside himself.

But it is believed he may have told the person to leave the flat to add to his sexual fantasy.

Erotic asphyxiation is the deliberate restriction of oxygen to the brain for sexual arousal.

Gareth had a small frame and fitted easily in the bag that measures 32 inches by 19.

Detectives are still trying to trace a mystery couple who visited the spy’s flat weeks before he died.

Police have confirmed that tests showed there was no trace of alcohol or drugs in his system.

His flat, in Pimlico, central London, did not appear to have been disturbed before the discovery of his body on August 23.

Police also scotched rumours about his double life as a gay transvestite after women’s clothes were found in his flat.

The cyclist fanatic and maths genius had been recruited by British security bosses after earning a university degree at 17.

He was just days away from completing a one-year secondment to MI6 from GCHQ, Britain’s eavesdropping base in Cheltenham, Glos.

Yesterday a pal said: “What a tragic waste of a brilliant life.”

An inquest will be held next year.

Bag spook died in 'Houdini' sex game

BODY-in-the-bag spy Gareth Williams suffocated after a kinky Houdini-style sex game went wrong, detectives said yesterday.

The naked MI6 codebreaker was a fan of claustrophilia - in which people get sexual pleasure from confined spaces.

Cops believe the 31-year-old maths genius died accidentally from lack of oxygen after he agreed to be locked in the 32-inch-long sports holdall by another person.

They reckon the person who zipped up the bag discovered him dead and fled the flat.

They have ruled out foul play but are still trying to trace the other person.

There were no signs of injury to Mr Williams' body and toxicology tests found nothing suspicious.

An examination of his two laptops showed he visited websites on claustrophilia.

He also had links to a bondage and sado-masochism website.

Two wigs and women's make-up were also in the flat in Pimlico, West London.

Mr Williams was zipped into the North Face bag and a padlock was snapped shut through two eyeholes in the handles - but the key was found inside.

Normally claustrophiliacs use a password in case of trouble.

It is thought Mr Williams, who did not have a girlfriend, died quickly in the hot bag, possibly while the other person was out of the room.

The key was then put in the bag which was moved to the bath.

Cops are hunting a couple who visited Mr Williams, originally from North Wales, before he died in August.

And CCTV showed him in a red T-shirt shopping at Harrods.

TVNZ : Spy's death still a mystery

Spy's death still a mystery

Reuters | October 29, 2010

Police probing the death of man who worked for Britain's Secret Intelligence Service MI6 said toxicology tests had found no traces of drugs or poisons, and the cause of his death remained a mystery.

Gareth Williams, 30, was found by police on August 23 at his top floor flat in Pimlico, central London, not far from the spy agency's headquarters, after he was reported missing.

Officers found his naked body in a zipped and padlocked holdall bag in an empty bath. Nothing was believed to have been stolen from the flat and there was no sign of any forced entry or disturbance inside.

Comprehensive tests had now been completed and had found no traces of any drugs, alcohol, poison or any other substances which would explain his death, detectives said.

"Mr Williams' death remains suspicious and unexplained and enquiries into the circumstances continue," London police said in a statement.

Detectives also repeated their appeal to trace a couple, both of Mediterranean appearance, aged between 20 and 30, who had paid a visit to Williams's flat about a month before he was found dead.

The mysterious nature of the death has led some to question whether he was targeted because of his work. However, the police inquiry is being carried out by its homicide unit, indicating they believe it is not related to terrorism or spy matters.

Williams was working for MI6, which deals with foreign espionage matters, on secondment from the Government Communications Headquarters, the government's eavesdropping service.

The Foreign Office has made no comment on the death, saying it did not make statements about anyone who might work for the intelligence agencies.

MI6 chief John Sawers said in the first ever public speech by the head of his spy organisation on Thursday that details of his staff and their work had to remain secret.
