Police attached to Lake Illawarra Local Area Command have released CCTV images after an armed robbery in Albion Park Rail last week.

About 10.40am on Thursday 4 Jul 2013, a man entered a chemist on Princes Highway armed with a knife.

He threatened a female customer with the weapon before demanding medication from a staff member.

The man fled the scene with medication and was last seen heading south on the Pacific Highway. No-one was injured during the incident.

Police were called and launched an investigation and they have now released security camera stills of a man who they believe may be able to assist with inquiries.

He is described as being of Caucasian appearance, about 170cm tall, with a thin build. He is shown in the images wearing a maroon-coloured beanie, khaki sloppy joe with maroon-coloured stripes across the arm, light grey track pants and white joggers with blue stripes. He is also shown riding a silver-coloured BMX bike.
