A teenager who staggered to hospital after a fight in the early hours of Sunday has died.
Amara Toure, of Manor Park, is thought by police to have been stabbed during a fight in Sutherland Walk, Walworth.
Detectives are renewing appeals for information following the fatal stabbing.
They have also named the victim as 18-year-old Amara Toure of Manor Park.
Police had been called at 4.15am on Sunday, 30 June to reports of a fight at Sutherland Walk. When police attended no victim could be found but they believe Amara had been involved.
He was treated for serious injuries but was pronounced dead at 7.23am.
A post-mortem examination held on Tuesday, 2 July gave cause of death as incisive wounds to the abdomen and blood loss.
Three men – two aged 22 and one aged 18 – were arrested on suspicion of attempted murder. They were taken to separate custody facilities and have since been released under investigation.
An investigation has opened up by the Met’s Homicide and Major Crime Command, led by Detective Chief Inspector John Massey. He said: “A young man has lost his life far too soon and we’re doing all we can to find who is responsible.
“We are keeping an open mind as to the motive but at this early stage of the investigation it does not appear directly linked to an incident that took place near Coldharbour Lane on Saturday afternoon.
“We are appealing to anyone who may have witnessed the incident itself or any altercations leading up to it, to come forward.
“Equally, we would ask that anyone with any information about what happened, no matter how small that detail, to contact us as this could really assist the investigation.”
Anyone with information is asked to call the incident room on 020 8721 4868.

A police statement added: “Bearing down on violent crime on the streets of London continues to be a top priority for the Met. Teams across the city are working tirelessly – day and night – to identify and pursue offenders, help bring perpetrators to justice, take weapons off the street, support victims, engage and reassure the public, and keep our communities safe.
“But police cannot solve this problem alone. The police, our partners and the public must work together to deal with knife crime and prevent further lives being lost. Communities have a vital role to play in tackling violent crime.
“We want to hear from anyone who may have information about people who may carry knives or firearms, or who are involved in organised drug crime and violence. This information could save lives in the future. If you aren’t comfortable speaking directly to the police, please contact the independent charity Crimestoppers. They do not ask your name or trace your call.
“If there are any young people who either have information about violence or knife crime, they can visit www.fearless.org where they can pass on information anonymously. Fearless is part of the Crimestoppers charity, and is also independent of the police.
“If you need help or information to support someone you suspect is involved in knife crime, or you want to assistance yourself, then you can visit www.knifefree.co.uk or LondonNeedsYouAlive.”
