Horrified eye-witnesses told how they heard a terrible “scream” as a 17-year-old lad was fatally stabbed “in the middle of his chest” outside a tube station.
They said his shirt “became red so quickly” after he was knifed outside Clapham South tube station in south London on Friday afternoon.
The victim, who has not been named, is understood to have been a student at nearby Saint Francis Xavier Sixth Form College.
Advertising consultant Andy Cronk, 52, who lives in an apartment overlooking the murder scene, said: “I saw him die.
“I heard a scream and Iooked out my window and he was lying on the floor bleeding from his chest.
“His shirt became red so quickly; I couldn’t tell you what colour it was, but I think he was from St Francis College.
“The boy didn’t move.
“He was a young black guy with curly hair.
“His friends were there with him looking completely confused, not knowing what to do.
“I saw the guy lying completely flat on the road.
“He was stabbed right in the middle of his chest.
“I’m still in shock.
“He got assistance really quickly from passers by.
“Then three police officers came to his assistance.
“They tried to resuscitate him with chest compressions.
“What really is shocking for me is that nobody wanted to step forward.
“The ones that we’re with him we’re talking about the incident, they know who did this.
“But they are too scared.”
The victim was the second teenager to be fatally stabbed in London in just 24 hours, and the 21st teen to be murdered in the capital this year.
London Mayor Sadiq Khan said: “my heart goes out to the family and friends of the two teenage boys fatally stabbed in the last two days: a 15 year old in Bellingham and a 17 year old outside Clapham South Tube Station. I am in contact with senior police officers and local representatives in both cases.”
There have now been 118 murders in the capital this year.
