A murder probe has been launched after a 15-year-old boy was stabbed to death in south-east London.
The teenage victim was found with fatal knife wounds in Woolwich New Road at about 5.20pm on Monday evening.
The stabbing happened in the busy shopping street in front of shocked onlookers, according to reports.
Social media footage showed people holding up sheets to give paramedics privacy as they tried to save the victim’s life. Horrific footage posted to Snapchat showed people performing CPR.
Officers were later called to a south London hospital after another 15-year-old boy presented himself there with a stab wound.
Police said his injury is not believed to be life-threatening. He has been arrested on suspicion of murder.
Greenwich council leader Dan Thorpe urged residents to hand over any social media footage of the fatal stabbing to police.
He said: “Following the awful incident in #woolwich this afternoon, we are liaising closely with @MPSGreenwich
“Please do not share footage on line but send through to the police & help us bring those responsible to justice. Our thoughts & prayers are with the victim and their family.”
Police said the boy's next of kin has been informed, though he is yet to be formally identified.
A section 60 order, which grants police additional stop and search powers, has been authorised for Woolwich Common, Woolwich Riverside and Glyndon wards until 10am on Tuesday.
Superintendent Petra Lazar, of South East BCU, said: “It is shocking and extremely saddening that a teenage boy has lost his life as the result of knife crime.
“My thoughts at this time are with the family of the boy who has died.
“This incident will understandably cause worry and concern to local residents and I would like to reassure them my officers are supporting the murder detectives in every way we can. Increased patrols will be carried out in the area over the next few days.”
