Emergency services were dispatched to the Second City Suite nightclub on Sherlock Street at the junction of Hurst Street, just after 9PM on Saturday (04/02), to reports of an incident.
On arrival, crews found a man, aged 30, with a gunshot wound to his leg – he was taken to hospital where he remains in a stable condition.
Two men, aged 18 and 22, were arrested on suspicion of assault and two more, aged 26 and 31, remain in custody on suspicion of firearms offences.
The immediate area has been cordoned off while forensic experts complete a detailed search and officers are trawling CCTV to establish what happened.
Detective Superintendent Tom Chisholm, from Force CID, said: “This is a fast paced enquiry, we have spoken to a number of witnesses and there is CCTV coverage in the area.
“I would urge anyone who has not yet spoken to us and has information which would assist to come forward as soon as possible.”
