The men were all white and spoke with local accents. Two of the offenders were dressed in what appeared to be police uniforms and the other man was in a suit.
One man in uniform was around 5ft six inches tall, in his 30s, of stocky build, with short, dark hair and clean shaven.
The second man in uniform was around 6ft two inches, of slim build and, clean shaven. The third man was roughly 5ft seven inches tall, in his late 40s or early 50s, of stocky build with a bald head and wearing a blue, tight-fitting suit.
