A man knifed to death after being chased through a south London council estate asked for a blanket as he lay "naked" dying in the road, a witness said.

Police were called to reports of a fight in the vicinity of Overton Road, Brixton, shortly before 6pm on Thursday.

A teaching assistant and mother who lives in the building where the victim, a man in his 20s, was seen running through the corridors, said she felt "shocked" and "saddened" by the young loss of life.

Margarida Lopes, 50, said: “They really jump across the balconies here, from above and over the brick walls. They used to do that some years ago.

"There was a man being treated here yesterday in the middle of the road.

"The thing that shocked me was that he was completely naked, and nobody was thinking about his dignity.

"He asked for a blanket twice and nobody was doing anything.

"I was about to say something and offer my first aid to support them, but the tape was up and everyone was on the balcony looking down.

"I don't know why he was naked, but I felt that was very wrong.

"He was conscious, and he was asking for a blanket. He was tilting his head up.

"It took a good hour before they took him away, so I don't know if he was severely injured and they were trying to stabilise him before taking him away on the stretcher.”

Another man, also in his 20s, was rushed to hospital to receive treatment for stab injuries. His condition has since been described as non-life threatening. 

The wreckage of an overturned car remains in the middle of a nearby residential street in Angell Town. 

A section 60 order granting police additional stop and search powers was in place across an area of south London, including Brixton, Clapham, Kennington and Vauxhall, until 9am on Friday.

No arrests have been made and enquiries continue, police said.
