A man who attempted a 'stick-up' at a service station armed with only a stick has left empty-handed.

Police have released a CCTV image of a man that may be able to assist with investigations into an attempted armed robbery at a service station in Browns Plains, in Logan, south of Brisbane.

About 7:20pm Tuesday, the man entered the Browns Plains Road business armed with a stick and made demands for cash.

"The man then threw the stick at the male attendant [and] then fled the store on foot," a Queensland Police Service media release said.

"No one was injured during the incident and nothing was stolen."

Investigations are continuing.

Police have asked anyone with information in relation to the matter to contact Crime Stoppers on 1800 333 000.
