A man was stabbed in the back of his thigh.

The man had to flag down passers-by for help after the attack, near Waterfields Recreational Ground in Ebury Road.

The incident - near Shaftesbury Road and Radlett Road - took place between 4.30pm and 5pm on Friday, August 10.

The victim, a man in his 30s, was approached by two men before one of them stabbed the victim in the back of his right thigh. He was taken to hospital for further treatment.

The offenders, described as black men, then ran off in the direction of Ebury Park.

Detective Constable Jon Holmes, who is investigating, said: “This assault has left the victim with lasting injuries. I am very keen to speak to any members of the public who may have witnessed the incident, particularly those who were driving along the Radlett Road and may have seen or been stopped by the victim.
