Clapham South stabbing: Boy, 17, knifed to death outside busy London Tube station

A 17-year-old boy has been stabbed to death outside a busy Tube station in south-west London.
Police and paramedics rushed to the scene outside Clapham Southstation shortly after 4.30pm on Friday.
The teenager was found suffering from a stab wound, Scotland Yard said.
He was taken to a south London hospital where he was pronounced dead a short while later.

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 said: “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.”
The youngster is the second teenage boy to be stabbed to death in the capital in 24 hours.
Jai Sewell, 15, died after being knifed outside a fast food takeaway 100 yards from his home in Bellingham, south-east London, on Thursday night.
Twenty-one teenagers have now been murdered so far in London this year.

Another witness, who did not want to be named, said he saw “a bunch of guys” shouting and appearing agitated, with one carrying a large knife.
He added that the area is usually noisy after students leave nearby Saint Francis Xavier College.
Photographs posted on social media showed a police cordon in place outside Clapham South station after scores of emergency services vehicles descended on the scene.

A Met Police spokeswoman said no arrests have been made.
She added: “His next of kin have been informed. Formal identification has not yet taken place and a post-mortem examination will be held in due course.
“Police remain on scene.”
Road closures were put in place and the station was closed while a police investigation was carried out.
