Three teenagers including a 17-year-old girl are due to appear in court charged with the murder of a 15-year-old boy who was stabbed to death in a street.
Kieron Carew-Donaldson, 18, of Brixton, and Darius Kwakye, 18, of Camberwell, plus the 17-year-old girl, have been charged with the murder of Temidayo Ogunneye.
Carew-Donaldson and Kwakye are also each charged with two counts of robbery, Scotland Yard said.
They will all appear in custody at Sutton Magistrates Court.
The victim, who lived with his family in Peckham, south London, was pronounced dead at 10.30pm on Wednesday - six hours after he was taken to hospital.
He was the fifth teenager to be stabbed to death in the city this year.
Police have said he was robbed of his BlackBerry phone about two hours before he was murdered in Cormont Road, Camberwell.
A post-mortem examination gave cause of death as loss of blood from stabbing injuries.
A third boy who was arrested on suspicion of murder was released on Thursday with no further action.
A fourth teenage boy was arrested that day on suspicion of murder. He has since been bailed until a later date in May.
