Did MI6 agents 'specialising in dark arts' kill spy in bag? New evidence emerges sparking fresh questions from the victim's family

• Gareth Williams's family believe a third party was either present when he died or broke into his home afterwards to destroy evidence
• Crime scene forensic scientist’s OWN DNA was found on Mr Williams’s hand
• Relatives wanted to know why the alarm was not raised when Mr Williams  failed to turn up at work - by then his body was badly decomposed for analysis
• It also emerged that a Mediterranean couple police wanted to speak to were irrelevant to Mr Williams’s death

The MI6 spy whose body was found locked in a sports bag may have been killed by a secret agent, his family said yesterday.

Their barrister suggested a sinister cover-up had left them with no way of knowing how and why Gareth Williams died.

One theory is that he died at the hands of a colleague. Another is that a foreign agent killed him because of his espionage work.

The discovery of the body in his flat near the Secret Service headquarters in London sparked a 20-month police inquiry that has drawn a blank.

At a public hearing yesterday, it emerged that the flat may have been swept clean of evidence, with no fingerprints or DNA anywhere.

It was also revealed that – far from being a back-office worker – Mr Williams had just completed training for deployment on operations.

Other revelations included:

• An expert seeking signs of forced entry said he was hampered because the front door had been taken from its hinges and locks removed;
• Pathologists still cannot agree on how Mr Williams died. The 31-year-old suffered no visible injuries and could not have locked himself in the bag according to police;
• DNA found on his hand that police rated as highly significant was in fact left by a bungling forensic scientist.
