Three door staff at a Belfast gay club were taken to hospital yesterday after being attacked with a weapon believed to be a knuckle-duster.

The staff – two women and one man – were treated for non-life-threatening head or facial injuries.

They were attacked shortly before 12.20am at the Union Street club Kremlin, which is said to be the city’s best-known gay venue.

Police investigating the incident have arrested two men and a woman, all in their twenties.

One of the attackers is said to have used a knuckle-duster.

Officers are working to establish a motive for the attack.

Anyone with information should contact police by calling 0845 600 8000 or Crimestoppers on 0800 555 111.
