A man accused of battering his father to death has told a court he was sleepwalking at the time.
Jules Lowe said he could not remember attacking his father
Jules Lowe, 32, of Walkden, Greater Manchester, admits causing the injuries which killed his father but says he cannot remember the event.
The body of 83-year-old Edward Lowe was found in the driveway of his home in Windmill Road, Walkden, on 30 October.
Manchester Crown Court heard he had 90 separate injuries consistent with being punched, kicked and stamped on.
Two hours after Edward Lowe's body was found, while police were at the scene, Jules Lowe was seen running onto the drive naked and shouting, Richard Marks QC prosecuting said.
He had cuts and bruises to his arms, feet and hands.
"I was on fine terms with my father - fantastic. I have always sleepwalked - it's never been a problem," Jules Lowe said.
He said he had sleepwalked frequently since he was a child.
Mr Marks said there appeared to have been a fight in the bedroom and the kitchen, before Mr Lowe's father was dragged or crawled onto the driveway where the attack continued.
Jules Lowe denies murder due to "automatism".
The trial continues.
