A man on trial for the murder of one man and the attempted murder of his partner has claimed that the couple sexually assaulted him.

David Kilcullen, 46, told the Old Bailey yesterday that he was acting self-defence after being assaulted while he was asleep. He denies the charges of murder and attempted murder.

He is accused of the fatal stabbing of Gerry Edwards, 59, and the attack on his partner, 56-year-old Chris Bevan. The couple lived in Bromley, south-east London.

The attack took place in March at the couple’s home in Page Heath Villas.

According to the Bromley Times, Kilcullen said yesterday he had only met Edwards once, six years ago, and had never met Bevan.

He claimed he was walking past their house when drunk on the night of the attack and decided to speak to them about a cable he had tripped over on their property in 2003.

He alleged he had fallen asleep in their front room and woke to find Edwards performing oral sex on him while Bevan fondled him.

Kilcullen said he went home but returned minutes after having a flashback about being raped by a man as a 14-year-old.

He admitted taking a knife to the couple’s home.

Bevan, who was hospitalised for months after the attack, said the allegations of sexual assault were “absolute bulls**t”.

Prosecutors said that Kilcullen had visited the home to steal and subjected the couple to homophobic abuse when he realised Bevan was at home.

It was claimed that he then began stabbing Edwards and turned on Bevan when he tried to intervene. Bevan survived the attack “by chance”, the court heard last week.

The court heard that after fleeing the property, Kilcullen drunkenly telephoned police and said he had carried out the attack because he was “skint”.

A broken bloodstained knife found at the property matched one in Kilcullen’s house, the court was told.

The court heard that the couple had lived together for many years and that Edwards, who was HIV-positive, was in poor health.

The case continues.
