Police have released vision of a woman they wish to speak to in relation to the attempted armed robbery of a service station at Heritage Park on November 20, 2017.

Around 2.45am, a woman 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.

No one was physically injured during the incident.

The woman is described as being Caucasian in appearance, aged in her early 20’s, with a slim build and long blonde hair. She was wearing a white t-shirt under a black hooded-jumper, black leggings and black shoes at the time of the incident.

Police are urging anyone who knows the identity of this woman, or may have information pertaining to her whereabouts, to come forward.
