ACT Policing is seeking witnesses and assistance to identify a woman who used a handgun in an aggravated robbery at Swinger Hill last month.

About 8:50pm on Sunday 16 February, police allege the woman entered the Friendly Grocer and threatened staff with a light brown handgun. During the incident, she demanded money and cigarettes from the teenage supermarket workers.

While no one was physically injured during this incident, it was terrifying for the staff involved.

A short time later the woman fled with a sum of cash and is believed to have departed the location in a white Toyota Corolla hatchback.

The woman police are seeking to identify is described as Caucasian in appearance with blonde hair and blue eyes. At the time of the incident, she was wearing a tan face mask, a black hoodie covering her head, blue denim shorts and white sneakers.

Police would like to speak to anyone who knows who the woman in the footage released today is.

Investigators would also like to speak with anyone who witnessed the event or who was in the vicinity of the Friendly Grocer during the robbery on 16 February.

Anyone with information is urged to contact Crime Stoppers on 1800 333 000, or via the Crime Stoppers ACT website.  Please quote 7978352. Information can be provided anonymously.
