This is the first picture of a man who was stabbed to death during a fight in a west London street.
Police have named the victim as 29-year-old Patrick Oyeri, who was stabbed in the liver when two groups of men allegedly began fighting in Rosebery Road, in Hounslow, on Monday.
Paramedics desperately tried to save Ugandan born Mr Oyeri following the attack at 3.35pm, but he was pronounced dead at the scene about 40 minutes later, police said.
A London Air Ambulance was also called.
The two groups of men had fled the street by the time officers arrived, the Met Police added.
Mr Oyeri’s death came during a terrifying day of violence on the capital’s streets, with another man stabbed to death in a street attack in Camden.
A 14-year-old schoolboy also died after he was blasted in the head with a shotgun in Forest Gate on Monday afternoon.
Corey Junior Davis died in hospital a day later, while he friend was taken to hospital with potentially life-changing injuries.
A police spokesman said: “Police were called at approximately 3:35hpm to the location following reports of a fight taking place between two groups.
