Luxury Audi stolen by 'violent' bandits on test drive

VIOLENT car thieves masquerading as buyers have punched a Brisbane man in the head and stolen his luxury car during a test drive.

The two bandits, who had a gun, then had the audacity to double-back in the stolen Audi A4 and pick up two mates they'd left at the owner's Runcorn home.

Police said four men arrived at the property about 9.30pm on Monday, but only two went on the test drive with the owner and his friend.

During the drive, the bandits produced the gun, punched one of the victims in the mouth, and forced the innocent pair out of the vehicle, police said.

They quickly returned to the owner's home, picked up their mates, and fled in the beige Audi, with Queensland registration 264 LBC. Police are still searching for them.

It was one of several police incidents in Brisbane's south overnight, including a home invasion in Tarragindi and the armed robbery of the Runcorn Tavern.

It is unknown if the incidents are related.
