School friends of murdered teenager Ben Kinsella arrived at his funeral today wearing colourful wigs and t-shirts bearing anti-knife crime slogans. 16 year old Ben was stabbed to death on a night out in North London, on June 29th. Outside St John the Evangelist Roman Catholic Church in London, Ben's sister and former Eastenders star Brooke Kinsella pleaded with others to learn from her brother's death. The 24 year old said: "Enough is enough. Do something now to make sure your brother, sister, son, or best friend's life doesn't end the same awful way." Speaking about the colourful outfits, Ben's friend Brooke Dunford, 16, said: "He was a funny, bright boy. He wouldn't have wanted everyone to wear black." Ben's friend Louis Robson, 16, the son of Birds Of A Feather actor Linda Robson, was with him as he died. Ben was stabbed several times after a fight in an Islington bar spilled out onto the street. Three teenagers have been charged with Ben's murder: Juress Kika, 18, Michael Alleyne, 18, and Jade Braithwaite, 19, have been remanded in custody until October 13. Last night an 18 year old boy was stabbed to death, becoming the 21st teenager to die a violent death in the capital this year.
