Detectives are appealing for witnesses and information following a stabbing in Perivale.
Police were called shortly after 21:00hrs on Sunday, 6 May to reports of a man stabbed on Buckingham Avenue.
Officers and the London Ambulance Service attended. The 43-year-old man was taken to a north London hospital where he remains in a stable condition; his injuries are not believed to be life-threatening.
At this early stage, officers believe that the suspect, who was driving a blue car, was questioned by a number of residents regarding the nature of his driving in the small residential street.
The suspect produced a knife before stabbing the victim and driving away.
Detectives would like to speak with anyone who saw the suspect leaving Buckingham Avenue and who is yet to come forward.
They would also like to speak with two women who were seen in a silver Volkswagen Golf shortly before the assault who may have valuable information.
Anyone who witnessed the assault is asked to contact officers at Ealing via 101 quoting reference 7026/6May.
There have been no arrests and enquiries continue.
