Couple arrested after two armed robberies in 30 minutes across Moreton Bay

Police have brought down a couple allegedly behind an armed robbery rampage north of Brisbane with two businesses hit in just 30 minutes.

Two people have been arrested after two armed robberies in the Moreton Bay region overnight.

Two people have been arrested after two armed robberies committed within 30 minutes of each other across the Moreton Bay region overnight.

Police allege a 28-year-old man entered a takeaway restaurant on Deception Bay Road just after 6pm and threatened workers with a firearm.

After a short confrontation, he left empty-handed and was seen entering the passenger side of a blue Ford Fiesta, driving north on Deception Bay Road.

The same man just after 6.30pm entered a business on Whitehorse Road in Dakabin and threatened staff, stealing cigarettes and money.

He again left the business in the blue Ford Fiesta which was seen by responding police, driving onto the Bruce Highway northbound from Deception Bay Road.

The car stopped on the highway and officers took the driver, a 36-year-old Petrie woman, into custody without further incident.

The male passenger allegedly ran from the car and with the assistance of the dog squad, was located at a house in Burpengary East.

Police located a firearm close to where the car was intercepted, and it will be tested to confirm if it is linked to the robberies.

The pair remain in police custody and are assisting with inquiries.

Investigators are appealing for anyone who may have CCTV or dash-camera footage from either Deception Bay Road or Whitehorse Road, between 5.30pm and 6.30pm Wednesday, to contact them.

Investigations are continuing.
