A GIRL was knocked unconscious and another punched in the face by a man at a university nightclub.

Police are appealing for information after the double assault at Essex University’s Sub Zero club on the Wivenhoe Park campus, in Colchester.

A police spokesman said: “Two females were assaulted.

One was punched in the face by the suspect on the dance floor.”

The spokesman said the victim sat down after the attack and told her friend what happened. The friend confronted the man and was also punched in the face, and knocked unconscious.

The attack happened at about 1am on Thursday, October 2, but the appeal has only just been issued.

Detectives have tried to identify the suspect through their own investigation, but now need help from the public to track him down.

He is aged about 20 or 21, with mousy hair and wore a grey jumper and jeans.

A university spokesman said: “Our Students’ Union takes incidents of this kind extremely seriously and is helping police with their enquiries.”

Anyone who was in the club that night, or who recognises the description, is urged to call PC Mike Heslegrave, at Colchester police station, on 101. Alternatively call Crimestoppers, anonymously, on 0800 555111
