Ben Kinsella was stabbed in Islington in June 2008
Friends of 16-year-old Ben Kinsella have told a court he was kicked to the ground by three youths who allegedly stabbed him to death in the street.
Ben was stabbed 11 times after leaving Shillibeers bar in Islington, north London, on 28 June last year.
A friend identified only as Claudia said Ben told the youths: "I haven't done anything", before he was killed.
Juress Kika, 19, Michael Alleyne, 18, and Jade Braithwaite, 20, from London, all pleaded not guilty to his murder.
The court heard that an argument broke out in the bar between a youth and Ben's friend, identified only as Alfie, 17.
Alfie said: "There was someone constantly staring at me. I just looked back and thought there was something wrong."
As he rowed with the youth, Mr Braithwaite and a bouncer became involved, he said.
Ben and Alfie were walking away from the bar when two people began to run towards them, the court heard.
Alfie said: "I saw Ben as I was jogging in the road. Ben was running beside me. He had blood coming from his shoulder."
Claudia, who was 16 when Ben died, said she was walking with Ben and Alfie outside the bar when someone mentioned a knife.
Speaking from behind a curtain, she told the court: "As I looked around, one of [the youths] had his hand down his trousers."
She added: "The boys started to run. Ben crossed the road and stopped running.
"Ben said: 'What are you coming over to me for? I haven't done anything.'"
Claudia told the court that a tall youth who had been involved in the earlier argument "kicked Ben in the belly and he fell to the floor".
The three youths encircled Ben, she said. "I thought they were punching him but I couldn't see."
The trial continues.
