Matthew Daley, 35, was detained on suspicion of murder after allegedly stabbing 79-year-old Donald Lock to death following a ‘minor car crash’ on the A24 at Findon, West Sussex in July last year. Daley, who admits killing Mr Lock but denies murder, is said to have repeatedly stabbed the keen cyclist in the head, back, neck and chest, severing his aorta, a  jury at Lewes Crown Court heard.

Jurors heard he looked ‘angry and crazy’ when he launched the ‘frenzied attack’ after Mr Lock’s Toyota apparently bumped into the back of his Ford as he drove home from a cycling meeting.

Daley was said to have been ‘flailing punches’ at Mr Lock. One witness said it was a ‘ferocious’ attack. They added: ‘Every second it looked like he stabbed him twice.’

Witness Andrew Slater told how he tried to remonstrate with Daley, telling him: ‘Come on mate, leave it out’.

Mr Slater told the court: ‘He stopped and that’s when I saw he had a knife in his clenched fist. I went, ‘Oh my God’.

‘As soon as I saw the knife, I backed away slowly, fearing he would attack me, and I got back into my car. Daley looked both ways and then carried on stabbing Don in the side of his back several times.

‘I was in my car completely shocked. I didn’t know what to do and I was shouting ‘Oh my God, oh my God’.

‘After a frenzied attack, Daley looked again up and down and, almost in a crouched movement, went to his car and wheel-span away. I went to Don and shouted, ‘Can you hear me? Can you hear

The court was told that, before the attack, Daley’s relatives had been ‘constantly on the case’ of doctors to try to get him better treatment.

And at one point, his desperate father said if he was not given proper care, he would go on to ‘hurt someone or worse’, the jury was told.

Daley was examined by a number of psychiatrists and was given mixed diagnoses ranging from autistic spectrum disorder with episodes of psychosis to paranoid schizophrenia. The court also heard he had stopped taking his medical action prior to the attack.

He is now being held in a medium-secure unit.

Jurors were told that it is not disputed Daley killed Mr Lock. However, he denies a single charge of murder. The jury was told that they could convict Daley, of Worthing, on a charge on a lesser charge of manslaughter.
