Detectives have issued a CCTV image of a man they want to question over a serious assault.

A 44-year-old man needed hospital treatment after being struck in the face in Espionage on Victoria Street, Edinburgh, in the summer.

The incident took place at around 2.50am on Sunday, July 31.

The suspect is described as a white man in his mid to late twenties.

He is around 6ft 2in tall with a slim build and short dark hair. At the time of the assault he was wearing a two-toned top and jeans.

Detective Sergeant Alastair Paisley said: "We're eager to trace the man pictured in the CCTV image and I would ask anyone who recognises him, or who may have witnessed the assault, to get in touch as soon as possible.

"This was a nasty assault in a busy nightclub so there will be many people who may have seen this."

Anyone with information can contact Police Scotland on 101 or Crimestoppers anonymously on 0800 555 111.
