Police are investigating the attempted armed robbery of a service station at Heritage Park in the early hours of this morning.

Around 2.45am a woman has entered the Waller Road premises and produced a knife while demanding money from the store attendant. The 32-year-old male employee immediately locked himself in an adjoining room.

She left the scene without obtaining any cash or property.

The woman is described as being aged in her early 20’s, Caucasian, slim build with blonde long hair and was wearing a white shirt under a long black hooded jumper, black leggings and black shoes.

No one was physically injured in the incident.
