A 17-year-old boy has died after being stabbed outside Clapham South tube station, Metropolitan Police have said.
Authorities were called to the station, in south west London, at approximately 4.35PM on Friday.
The teenager was then taken to a south London hospital, before being pronounced dead at 5:23PM.
Charity director Robin Pritchard said he moved through a crowd and saw the victim lying in a pool of blood while someone provided CPR.
The 47-year-old told the Press Association: “I saw the guy on the floor, a pool of blood like he’d been stabbed in the stomach, his clothes were soaked.
“It was strangely calm and quiet. I think everyone was in shock. Lots of kids there from the local college.
“All I really registered were grey tracksuit bottoms which were soaked with a pool of blood coming from his waist like he’d been stabbed in the stomach.”
Officers are in the process of informing the victim’s family, although formal identification has yet to take place.
“A post-mortem examination will be held in due course,” a statement from the Metropolitan Police reads. “Police remain on scene. No arrests. Enquiries ongoing.
“Road closures are in place and Clapham South Station has been closed.”
This death comes one day after a 15-year-old, named locally as Jai Sewell, was stabbed to death in Bellingham, south east London.
The killing marks the 115th homicide in the capital so far this year.
