A 17-year-old boy who was stabbed to death on a street in central London, has been named as Josiph Beker.
The teenager, also known as Yousef, was with friends outside a KFC on Edgware Road when a fight broke out between two groups on Tuesday, police said.
He was stabbed during the confrontation and died in hospital later.
Police said they were keeping an “open mind concerning motive” and urged any witnesses to come forward. No arrests have been made.
A post-mortem examination concluded Josiph died from a stab wound to the chest.
Det Ch Insp Andy Partridge said: “Lots of people were in the area at the time and may well have seen what unfolded.
“We need them to do the right thing and get in touch with what they saw along with any images or moving footage captured before, during or after the attack.”
A 14-year-old boy accused of a stabbing murder has been remanded to a secure unit.
The teenager, from Barking, appeared at Thames Magistrates’ Court on Saturday morning over the killing of Santino Angelo Dymiter, from Plaistow.
Eighteen-year-old Mr Dymiter was found injured on the afternoon of 26 August by emergency services at Chadd Green, east London.
The judge remanded the 14-year-old to appear at the Old Bailey on Tuesday.
The boy, who cannot be named for legal reasons, is also accused of having a knife in a public place.
