Ralph Millward was found dead outside Marks and Spencer in Westbourne
A jury has heard a teenager describe how his three friends kicked a Big Issue seller to death when the man refused to give them a cigarette.
Ralph Millward, 41, had been sleeping rough outside Marks and Spencer in Westbourne, Bournemouth, when he was attacked on 8 May last year.
Three boys, two aged 17 and another aged 15, deny murder.
A police DVD, in which the youth said he tried to stop the attack, was shown to Winchester Crown Court.
The teenager and his friends cannot be named because he is aged under 18.
The court has heard how the four youths had bought and drank two bottles of cider and two bottles of vodka on the night of the fatal attack.
At about 0130 BST they went to find Mr Millward to ask him for a cigarette because one of the then 16-year-olds had done so in the past, the jury heard.
In the police interview, showed in the court, the boy said: "He was just saying no, no, no.
"I don't know who started kicking him, I didn't see.
"He was crawling trying to get his sleeping bag in front of him.
"I don't think they realised how much they were hurting him because of the drink or something."
Timothy Mousley QC, prosecuting, told Winchester Crown Court on Tuesday that Mr Millward, who was a "familiar local character", was discovered lying dead in bushes by two outreach workers the next morning.
He had died from multiple blunt force injuries and a was found with a supermarket trolley on top of him.
The trial continues.
