A man was hit in the face with a glass while out in Newcastle.
The 22-year-old was on a student night in House of Smith - next to Madame Koos and Floritas - on Collingwood Street.
He was on the dance floor when, after a small argument, he was hit in the face - with what is believed to be a glass.
The victim needed stitches and was taken to hospital with a cut to his face.
The attacher is described as being 21, around 5ft 11ins tall of silm and athletic build. He had short brown hair and a receding hairline. He was wearing a white t-shirt - possibly with a motif on the chest.
Police are appealing for any witnesses to the assault or anyone who saw a disturbance on the dance floor, or knows who is responsible, to get in touch with them as soon as possible.
Anyone with information is asked to contact police on 101 ext 69191, or Crimestoppers anonymously on 0800 555 111.
