A man and a woman in their 20s both sustained minor injuries “from what was believed to be a glass” in two separate assaults on the dance floor between 01:00 and 01:30.
The woman was taken to hospital by ambulance for treatment.
A 27-year-old man was later arrested on suspicion of grave and criminal assault and has since been released on police bail whilst enquiries continue.
