Ben Kinsella was stabbed in Islington in June 2008
CCTV footage of teenager Ben Kinsella moments after he was fatally stabbed has been shown to a jury in the trial of three men charged with his murder.
He was stabbed 11 times after leaving a bar in Islington, north London, in June last year, the Old Bailey heard.
Juress Kika, 19, and Michael Alleyne, 18, and Jade Braithwaite, 20, all from London, have all pleaded not guilty to the 16-year-old's murder.
Ben's sister, former EastEnders actress Brooke Kinsella, was also in court.
'Argument broke out'
The court heard that Ben died after leaving the Shillibeers bar in York Way on 29 June 2008.
An argument had broken out in the bar between a youth known only as Alfie and a friend of Mr Braithwaite's named Osman Ozdemir, the court heard.
Prosecuting, Nicholas Hilliard QC said: "Alfie and Ben Kinsella knew each other although Ben Kinsella was not part of the dispute."
A boy called Michael allegedly heard Mr Braithwaite say: "Tell your boy if he wants trouble, I've got my tool on me and it will open you up."
The court heard that Ben and his friends left the bar shortly before 0200 BST, when they were chased by the defendants. They allegedly caught up with Ben and killed him.
Mr Hilliard said: "They managed to catch up with the deceased, knocked him from his feet at the rear of a parked van and, as he lay on the ground, launched a lethal attack upon him in which a total of 11 stab wounds were inflicted."
One of the stab wounds was to Ben's heart, two went into his lungs and damaged an artery, the court heard.
CCTV footage showed Ben stumbling from behind a van after being fatally wounded.
Mr Hilliard added: "No-one suggests Ben Kinsella was anything other than totally blameless.
"This was not a war zone far away. This was Islington in London."
The trial continues.
