A man in his mid-20s had to be taken to A&E after a fight in town in the early hours of Sunday morning.
Jersey Police believe four men - including the victim - were involved in the incident on Conway Street at around 1am on Sunday 6 March.
The man assaulted suffered injuries to his face and hands, and didn't know the other men involved.
Officers haven't been able to provide a description of them, but they say a few passers-by were in the area at the time, and several cars also drove past.
Anyone who was in the area at the time, or who has information about the fight, is asked to call Jersey Police on 01534 612612 or contact Crimestoppers anonymously on 0800 555 111.
