Camberwell murder: Boy 'robbed' before stabbing
A teenager was robbed of his mobile phone an hour before being stabbed to death in south London, police believe.
Temidayo Ogunneye, 15, was attacked behind a block of flats in Cormont Road, Camberwell, on Wednesday.
Police said his Blackberry appeared to have been taken at 1440 BST and he went back to the area at 1600 BST to find it.
Three teenage boys are still being questioned about his murder. A fourth teenager has been released with charge.
A witness, who did not wish to be named, said a fight had broken out between two sets of rival gangs and the teacher from a nearby school had tried to stop the violence.
One resident reported seeing Temidayo's friend using a scarf to stop the blood.
Det Ch Insp John McFarlane, of Scotland Yard's homicide and serious crime command, said there was "quite a disturbance" after the attack.
"A large number of youths were hanging around the area," he said.
"I would like to now specifically appeal for anyone who may have witnessed the incident in which Temi was robbed to contact the police," he added.
He also asked anyone who saw a youth running down Halsmere Road shortly after 1600 BST, or a group of youths lingering around Cormont Road, to come forward.
Temidayo, who came from Peckham, south London, was the fifth teenager to be fatally stabbed in London this year.
