Police have released still images of a man they are seeking in relation to the armed robbery of a convenience store in East Ipswich.

Around 8.30pm a man entered the store on Jacaranda Street, where he approached the female attendant armed with a knife and made demands for cash and cigarettes.

The man left the store with money and cigarettes, heading across Jacaranda Street where he jumped a fence and was last seen running across sporting fields towards Joyce Street.

At the time he was wearing blue tracksuit pants and a white hooded shirt with a white scarf covering his face.

The woman was not injured.
