The mother of a teenage boy stabbed to death during an attack by a group of youths in north London has appealed for an end to gang violence.
Police said the killing was "vicious"
Martin Dinnegan, 14, was stabbed in the chest in Tollington Way, Islington, on Tuesday night and died at the scene.
His mother Lorraine said the killing was "horrendous" and questioned how many more stabbings there had to be.
Seven young Londoners have been killed as a result of either knife or gun crime in the last eight days.
Mrs Dinnegan said: "I've just been speaking to one of Martin's friends and he says it's because apparently they were looking at each other in the wrong way."
"Before he knew it, there were lots of boys fighting and he said he just looked and Martin was lying on the ground.
"It's just totally horrendous.
"Why is it happening, why is it still happening? How many more victims are there going to be?"
