Three Brisbane north businesses were hit by armed robbers in the space of just 25 minutes.

Three strikingly similar armed robberies took place across North Brisbane last night within the space of just 25 minutes.

Armed with a baseball bat in a desperate attempt for cash and cigarettes, one man entered a shop on Albar St, Wavell Heights at 6.10pm and left empty-handed.

Just 20 minutes later a robbery occurred 4.6km away.

A man, armed with a baseball bat, entered a service station on Webster Rd at Chermside West before he demanded and stole cash and cigarettes.

Fifteen minutes later, a man entered a supermarket on Handford Rd at Zillmere – just 5.5km away. He was also armed with a baseball bat and demanded cash.

Officers from the Queensland Police have stated that they believe the same man who attended the service station also broke into the supermarket.

A spokesman for QPS however said that a link between all three robberies could not be confirmed and they were currently under investigation.
