Cops are hunting a lout who attacked a young man in a bust-up outside a city centre fast-food restaurant.

The 22-year-old was battered so badly he was rushed to hospital with serious injuries.

Police today released a CCTV image of a man they believe may hold vital information about the incident, which took place outside KFC in Argyle Street.

It happened at around 2.30am on Monday January 25.

Detectives are keen to speak to the man shown in the image as they believe that he may be able to assist with the investigation.

He is described as being "white European in appearance" and in his mid to late 20's.

Detective Constable Gordon Walker, from Greater Glasgow CID, said: "A violent assault like this within Glasgow city centre cannot be tolerated.

"We seek the assistance of the public in tracking down those responsible.

"Anyone with information is asked to contact Greater Glasgow Police on 101 or alternatively contact Crimestoppers on 0800 555 111 where information can be passed anonymously."
