A man was sexually assaulted before being repeatedly punched in an attack at a Wetherspoons pub.
The victim was on the dance floor at the Union Rooms in Plymouth when he was inappropriately touched by a man on September 12.
When he confronted the individual, he was punched several times and sustained a cut to his face, which required medical treatment.
Devon and Cornwall Police have since released an image of a man who they believe will be able to help ongoing enquiries into the incident.
The force has urged anyone with information to contact them via their website or by calling them on 101, quoting crime reference 50250238198.
Alternatively, information can be shared anonymously to the independent charity Crimestoppers by calling by calling 0800 555111, or via www.crimestoppers-uk.org.
