Police have renewed their appeal to find the killer of a man who was tied up, robbed of £1,000 and left to die in his north London flat nine years ago.
Intruders stole Mr Holmes' bank cards
Alan Holmes, 53, was last seen by friends after they dropped him off at his home in Parkway, Camden, after dinner on Christmas Day 1995.
Police believe intruders tied Mr Holmes to a bed and stole cash cards on Boxing Day. He was discovered 10 days later.
A reward of £5,000 has been offered for information leading to a conviction.
Police were alerted to Mr Holmes' disappearance after he failed to turn up for work at the Kentish Town police station garage.
Officers found him lying face down with his hands and feet tied to a bed in the kitchen of his flat.
He was critically ill and died the following day. A post-mortem examination gave the cause of death as "blood clotting from immobilisation and dehydration".
Police believe intruders forced him to hand over two bank cards and PIN numbers before stealing £1,000 from his accounts.
Five men were arrested in 1996, but none were charged.
Detective Inspector Anthony McKeown said: "This was a tragic Christmas murder, and nearly nine years on the investigation is still open, and for the sake of the victim and his family, we are still committed to solving this terrible crime."
