Anthony Morley, 36, the first winner of the Mr Gay UK competition, cut up the cooked flesh on a chopping board before chewing on a slice while the body of Damian Oldfield lay upstairs in a bedroom, Andrew Stubbs QC, prosecuting, told Leeds Crown Court yesterday.

The remains of what he had sampled were later found in a bin bag after Morley, wearing a dressing gown and flip flops, and with his hands heavily bloodstained, told staff at a nearby takeaway that he had killed someone who had tried to rape him.

Police discovered the body of Mr Oldfield face up and naked on the floor of the bedroom at Morley's home in Bexley Avenue, Harehills, Leeds, with two knives lying on the bed.

His throat had been cut and he had been repeatedly stabbed.

Morley told arresting officers: "At least he won't be able to do it again."

He denies murdering Mr Oldfield, 33, an advertising salesman, of Bramley, Leeds, in April but his defence counsel Robert Smith QC said he accepted he was "at the very least guilty of manslaughter".

Mr Smith told the jury that Morley admitted cutting Mr Oldfield's throat and stabbing him as well as removing skin and flesh with a knife or knives, preparing and cooking sections in the kitchen and sampling by chewing a section.

The issues for them would be whether it was manslaughter rather than murder because Morley was provoked to lose his self-control by reason of a sexual assault, or whether he was suffering from an abnormality of mind at the time of the killing which would substantially diminish his responsibility.

Mr Stubbs told the jury Mr Oldfield was openly homosexual and described as bubbly, outgoing, flirtatious and promiscuous – comfortable with his sexuality unlike Morley.

Although he had won the first Mr Gay UK Competition in 1993 he was troubled by his sexuality. Morley had homosexual affairs in the past but he also had relationship with women.

It appeared from text messages exchanged between Mr Oldfield and Morley on April 23 that they had had some kind of relationship in the past.

Morley told the other man he had never been happy being gay and had tried being bisexual. He suggested to Mr Oldfield that they try again but said he wanted to take things slow.

That night Mr Oldfield returned to Morley's home with him and Morley prepared a meal for them before they went upstairs to the bedroom.

Around midnight Morley received a phone call from a friend but said he could not talk as he was in bed with someone.

It was in the early hours of the morning he walked into a takeaway in Roundhay Road and confessed to killing someone.

Mr Stubbs said it was the Crown's case that Morley had subjected Mr Oldfield to a violent attack in which his throat was cut and he was stabbed repeatedly in the back and chest, sometimes the wounds overlapping.

"At some stage Mr Oldfield was face down on the floor and Mr Morley continued to stab and stab and stab him until he died. Even when he was dead the attack continued until finally Mr Morley cut parts of flesh from the body."

He warned the jury not to let the horror of what had happened cloud their judgment.

Morley had carved a piece of flesh off around one of Mr Oldfield's nipples. A bank card had been left over the wound.

As with that piece, part of an area of flesh carved from the thigh was found in the bedroom. But police realised some was missing.

"From a chopping board on one of the kitchen units six pieces of cooked flesh, which had been seasoned with fresh herbs and fried in olive oil, were recovered. The flesh was human in origin."

Tests revealed the DNA matched Mr Oldfield as did a further piece of flesh, apparently chewed, with Morley's saliva on it in a bin bag.

He said it appeared after the killing Morley had carved away a piece of flesh, taken it downstairs, seasoned it, fried it and tried to eat it.

When he told staff at the takeaway of the killing he was asked why and replied: "Someone tried to rape me so I killed them."

He told police who arrived he had stopped a man trying to rape him and when asked how said: "I'm a chef; how do you think I stopped him."

He said he had stabbed him lots of times and when arrested added: "I know what I have done is wrong. He tried to rape me; at least he won't be able to do it again. This has happened to me before."

The trial continues.
