The boys were stabbed near the Southside shopping centre
A 15-year-old boy has been stabbed to death following a fight in a busy high street in Wandsworth.
The boy was rushed to hospital along with a 16-year-old boy who also suffered a knife wound, but he later died.
Officers on patrol came across a number of males fighting in Garratt Lane shortly before 5pm on Thursday close to the Southside shopping centre.
They discovered the two stabbed teenagers near the Garratt Lane Burial Ground.
Two males have been arrested. One who had suffered a head injury that did not require hospital treatment was arrested on suspicion of GBH.
The other was arrested on suspicion of affray.
A police spokesman said that "full inquiries into the circumstances continue" and specialist crime squad detectives have been informed.
London mayor Sadiq Khan described the killing as "appalling and tragic", and urged people to help the police.
Mr Khan said: "We must all redouble our efforts to end the scourge of violent crime on our streets.
"Those responsible for this dreadful crime will be caught and prosecuted."
Police said there is an "extensive crime scene" in place and nearby roads have been closed.
A Section 60 Order was authorised for the whole of Wandsworth an hour after the incident.
The Metropolitan Police is asking anyone who has information, video or images that could help with the investigation to call 101 reference CAD 5042/29 Oct.
