Police are appealing for anyone who was at the party at the town's working men's club to contact them.

A 22-year-old man at the event was stabbed in the thigh outside the club in an apparently unprovoked attack and needed 15 stitches to the wound.

A fight had broken out between two men when a third man stabbed the victim just before 0100 GMT on 1 February.

The man ran back inside the club after the attack where he lost consciousness.

Police described the man responsible for the assault as white, about 5 ft 11 in tall, of stocky build and with short black hair.

Anyone who was in the area at the time of the incident should contact Surrey Police.
