Police officers were called to Corinne Road near the junction with Brecknock Road just before 9.30pm. They found the victim with knife injuries and gave him first aid but he died at the scene 40 minutes later.

A motorcyclist who was passing the junction of Lady Margaret Road and Brecknock Road shortly before the incident told the Gazette this morning he believed it had been over a stolen mobile phone.

Speaking at the scene, Felipe Carvalho, 31, said: “I had just finished my job and was on my way home because I live nearby.

“The attacker had a black bag and pulled a big knife out of it. It was a big crocodile type knife about 60cm long.

“The other guy was shouting: ‘Give me my phone back’

“The person with the knife was black and about 18 to 23. The man whose phone had been taken looked Indian and was chasing him, then the guy stopped and showed him the knife.

“I was so scared. I stopped and was trying to help him. I said: ‘Forget this, it’s crazy.’ I’m so sad now because this situation is all over a phone.

“The last I saw was the guy stop and take a knife from his back, then they turned right on to Corinne Road. That was the last I saw.

“I wish I’d done more to help now but I was so scared when I saw the knife.”

The victim is the fourth person to be stabbed to death in the borough this year after Steve Frank Narvaez-Jara, who was knifed at a New Year’s party in Old Street, Kwasi Anim-Boadu, who was killed on the Andover Estate in April and Marcel Campbell who was attacked at rush hour in Upper Street the following month.

Scotland Yard said the victim’s next of kin have been told and a post-mortem is being scheduled.

No arrests have been made and detectives from the Met’s Homicide and Major Crime Command are investigating.
