Ballarat police are hunting a man who punched another man in the face at a nightclub earlier this month.
The victim was at the Bluestone nightclub on Mair Street, when he was assaulted by another man he did not know at 1.30am on September 1.
The incident occurred in the upstairs male toilets on the nightclub, where a short, stocky male with dark hair punched the victim to the face.
He suffered facial injuries and had two teeth knocked out of his jaw.
Several witnesses have already come forward to police but investigators have asked anyone else who witnessed the attack to come forward.
Anyone with information can contact Constable Ben Fraser on 53366000.
