Three men wearing Roman-style fancy dress costumes carried out a "vicious and unprovoked" attack in Aberdeen, police have said.

The men were wearing shorts and togas or Roman-style garments.

They approached a man on Windmill Brae near the junction with Bath Street and attacked him at about 0130 GMT.

Grampian Police said the men may have been part of a larger group, and had left the victim with facial injuries which needed hospital treatment.
