A man was found unconscious in the street after he was attacked in Glasgow's financial district.

The 42-year-old was discovered in Cadogan Street at West Campbell Street at around 9.15pm on Sunday by a member of the public who called an ambulance for him.

He was taken to Glasgow Royal Infirmary where he remains for treatment for facial injuries.

Police Scotland said it has been established that the man was attacked by another man following an argument between the two in Cadogan Street a short time earlier.

The suspect is described as white, tall, skinny, with dark hair and stubble. He was wearing a grey jumper.

Detective Constable Nicol McPherson, Stewart Street CID, said: “The man who called the ambulance left the scene before it arrived and took the injured man to hospital, so we are keen to speak to him about what he may have seen or knows about what happened.

“Officers have been checking CCTV in the area and we know that Cadogan Street at West Campbell Street can be quite busy around that time of night. There is a local soup kitchen not far from where the attack took place so it is possible that someone there saw the attack and could help our investigation.

“I would ask anyone who has any information they think may assist our enquiries to contact the officers at Glasgow City Centre CID via 101. Please quote incident number 4103 of Sunday 9 September 2018 when calling. If you don’t wish to speak to the police direct, then Crimestoppers can be called in confidence on 0800 555 111.”
