Police have released an image of a man they believe may be able to assist with investigations into an armed robbery at a Higgins pharmacy earlier this year.

Police allege the man entered the Advantage Chemist at about 11.10am on February 26, threatened staff with a gun and demanded medication.

Police say no one was injured as the staff complied and the man left on a bicycle.

He is described as Caucasian in appearance with a solid build. He was wearing a red top under a grey hoodie, black pants, a dark cap, dark sunglasses and carrying a dark backpack. The bicycle is described as a dark hardtail mountain bike.

Anyone who recognises the man should contact police via the Crime Stoppers website.
