A 29-year-old man has been stabbed to death in a fight in south-west London.
He was stabbed at the junction of Gowan Avenue and Munster Road in Fulham in the early hours of Saturday and died at the scene.
Neighbours said they heard an argument unfolding at 00:30 GMT, before police and paramedics arrived.
A friend of the victim's described him as a "good and big man" and said: "At the age of 29, you don't do silly things like this, knife crimes."
Tracing the family
The friend, who asked not to be named, said he was not aware of any similar violent incidents in the residential area but added: "There might have been a stabbing in this area, don't get me wrong, but they are normally with kids, not people our age."
Greg Hands, the Conservative MP for Chelsea and Fulham, said he had thanked the local "hero" who gave CPR to the victim and also thanked a group of girls from New Zealand who had stopped to help.
Have thanked the local Fulham man who gave CPR to the victim in the fatal stabbing last night. A hero - and the group of girls from New Zealand (ironically) who helped too. A traumatic experience for all of them, but we thank them.— Greg Hands (@GregHands) March 16, 2019
Efforts were still being made to contact the victim's family, police said.
No arrests have been made.
Det Ch Insp Glen Lloyd, said: "We are appealing for information from those who were out and about in the area at the time of the attack and saw anything of note.
"My team is particularly keen to trace a light skinned black male, approximately 6ft tall who was seen near the scene at the time."
The victim was stabbed in the same street where TV presenter Jill Dando was murdered in 1999.
Ms Dando was 37 when she was shot in the head on the doorstep of her home in Gowan Avenue on 26 April. Her murder remains unsolved.
