Avon and Somerset Police are appealing for help to identify a man who they believe has useful information to help them following an assault at Mambo Bar and Nightclub in Mill Lane.
The incident happened on 22 July at about 23:15 near to the outdoor bar on the ground floor – the smoking area.
Police say there was discussion between four men when the victim was pushed over inside the club.
All four were requested to leave the club and the victim was then approached by the man who had pushed him over and punched him in the face, suffering a cut to his face, which required hospital treatment.
Police are keen for the man pictured to contact them or for anyone that recognises him to get in touch.
If you can help, call 101, quoting reference 5217167887.
