A bar worker suffered a serious facial injury after he was assaulted in a popular music venue.

The 25-year-old man was working in King Tut's Wah Wah Hut on St Vincent Street, Glasgow, when the unprovoked attack took place at around 10.40pm on Thursday.

The victim was taken to the Glasgow Royal Infirmary, where he was treated for his injuries before being released.

Detectives investigating the incident are now appealing for witnesses to come forward and have released a description of the suspect.

He is described as around 6ft with a medium build and long dark hair worn in a ponytail.

Detective Constable Alistair Donaldson, of City Centre Police Office, said: "Officers have been carrying out enquiries into this incident and have gathered CCTV footage which we will study to gather more information and identify the man responsible for this violent and unprovoked attack.

"At this time, I would urge anyone who witnessed this incident take place within the music venue who has not yet spoken to police to please come forward as they may have information that is significant to our investigation.

"This is not the type of incident staff or any member of the public should be subjected to and I would directly appeal to the man responsible to come forward.

"Anyone with any information should contact City Centre Police Office through 101."
