A murder hunt is under way after a young butcher was stabbed to death in his shop.
The victim, thought to be in his early 20s, died at the scene after the attack in north London on Thursday.
Officers are yet to make an arrest, a Scotland Yard spokesman said.
Police were alerted to the attack at Halal Food Direct, 16 The Broadway, Wood Green, shortly after 3pm.
The victim, a member of staff at the business, was treated by paramedics but died at the scene, Scotland Yard said.
The attacker fled the scene after the stabbing, which police believe occurred following a dispute in the shop.
A senior investigating officer, Detective Chief Inspector Steven Lawrence, said: "At this early stage it appears there was a dispute in the shop which resulted in the victim being stabbed. The male suspect then made off from the premises on foot.
"This incident occurred in a busy area in the middle of the afternoon, and we need to hear from any witnesses who have not yet come forward.
"Did you see anything that may be of use? Did you see in which direction the suspect ran off? It is essential that anyone with information contacts the police as soon as possible."
Anyone who could help was asked to call the incident room on 020 7321 9290, or, if wishing to remain anonymous, Crimestoppers on 0800 555111.
