Investigators have been told an unknown man attended the High Street business about 9.30pm on Saturday 13 March.

The man, who was armed with a knife, threatened a male and female employee before taking a sum of cash and fleeing on foot.

Neither the 27-year-old woman or 38-year-old man were injured during the incident.

Investigators have released CCTV of a man who they believe may be able to assist with their enquiries.

The man was wearing a grey hooded top with dark coloured sleeves, blue tracksuit pants, brown work boots, and had a white cloth covering his face.

He was also wearing a large blue glove on his left, similar to a welding glove.

The man was described as being above average in height and had a stocky build.
