Detectives have released a new image of a woman who may be able to assist with their investigation into the armed robbery of a Kippa Ring gift shop last month.

Around 12pm on August 3 a woman entered the Anzac Avenue business and produced a knife, demanding money from a female staff member.

The employee complied with the demands and the woman stole a sum of cash before fleeing the scene on foot.

No one was physically injured during the robbery.

The woman is described as Caucasian, approximately 165cm tall, of thin build with sun weathered skin, curly grey/brown hair tied in a bun and discoloured front teeth.

Police believe the woman might also be able to assist with a stealing incident also on Anzac Avenue in August at Mango Hill.
