Witnesses have described seeing a 17-year-old boy, who was stabbed and killed in London, being attacked by a masked man.

Police were called to reports of a fight at about 10.35pm on Friday night in Isleworth and found a boy who had suffered stab wounds.

The officers carried out first aid before paramedics arrived, but the teenager was pronounced dead outside a block of flats on Union Lane a short while later.

A couple who called the police described finding the bloodied victim on the ground after the fight.

The husband and wife said they heard shouting and looked out of their flat to see the teenager being assaulted by two people.


The pair, neither of whom wished to be named, said one of the perpetrators had his face covered.

The husband said: "It was one guy who was massive with, like, a mask on his face and another small guy. They were kicking him (the victim), but it was dark so it was hard to see exactly what was happening."

By the time the couple went downstairs to the scene they said the two attackers had left.

A post-mortem will be carried out in due course.

Officers have "begun the process" of informing his next of kin, the Met Police said.

A murder investigation has been launched, but no arrests have been made.
