A vulnerable man was punched in a "nasty" unprovoked attack.

The 53-year-old man, who suffers with mental health issues, was attacked outside the Crystal Nail Bar, in Stonecot Hill, on Saturday, April 13, between 5pm and 5.30pm.

He had just been to the Game Exchange shop when a man walked towards him and punched him in the face.

The victim needed hospital treatment after his lip was cut.

Police believe the attacker, who was swearing loudly as he walked along the street, then got on the 413 bus towards Sutton.

The attacker is described as a white man with a brown moustache. He was wearing a black hooded tracksuit.

Detective Constable Aaron Moon, of Sutton police, called it a nasty and unprovoked attack.
