A MAN was the victim of an "unprovoked" attack on a busy city centre street.

The 51-year-old was headbutted outside the Jamhouse on Edinburgh's Queen Street around 3am on Sunday October 11.

As he was standing outside waiting for his partner, a man who had been inside the music venue came out and headbutted him, causing serious facial injuries.

Police have now appealed for witnesses.

The suspect is described as white, in his 50s, around 6ft tall with a stocky build and shaved head.

He was wearing a dark striped shirt and dark trousers.

Detective Constable Carole Sneddon said: "The victim was assaulted without any warning and sustained a serious facial injury.

"We are now conducting various lines of inquiry to trace the male responsible.

"Anyone who witnessed the assault or who has information relevant to this investigation is asked to contact police immediately."

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