Police have released an image of a man they want to locate after a 27-year-old was fatally stabbed inside a car in west London.
Officers were alerted to reports Bajram Luli was injured in Sudbury Heights Avenue, Greenford at about 5.30pm on Monday.
Metropolitan Police and paramedics discovered him with knife wounds in a white Kia vehicle.
Albanian media reports said Mr Luli had recently moved to the UK from the country. He was taken to hospital where he died a short time later.
A local resident whose CCTV caught the incident told the Standard how a Kia vehicle reversed down the road before one person jumped out and fled.
Shortly afterwards the victim staggered out of the car holding a wound near his stomach.
Detective Chief Inspector Jim Shirley issued a picture of a man entering a nearby Tube station in Sudbury.
He said: "This is a very clear image and I would like anyone who recognises this man to contact police immediately.
"The investigation is continuing at pace and we are working hard to secure justice for the family and friends of the man who was fatally stabbed."
