Incredible footage has emerged of a Grand Theft Auto-style showdown between armed fugitives and advancing police on a busy motorway.

The shirtless men run wild into oncoming traffic, waving their weapons at drivers and firing shots as officers approach.

One fugitive runs straight into a vehicle's path, bouncing off the boot and crashing onto the concrete.

His weapon spins off in the opposite direction, giving cops the opportunity to pounce.

"Drop the gun, drop the gun," one officer can be heard shouting during the chase.

"Shots fired, shots fired," he shouts.

The men attempt to steal one car when it slows but just as they open the vehicle's doors, it begins to speed up and knocks them out of the way.

"Confirmed, two in custody," an officer says, as the fugitives are pinned to the ground.

The four-hour pursuit began in Caboolture, north of Brisbane, in Australia on February 2 2015.

But footage of the dramatic showdown only emerged this week.

The men were forced to abandon their getaway vehicle - a stolen car - when it hit road spikes.

During the four-hour pursuit, cops said the men carjacked three vehicles.

Police say several shots were fired at officers and other vehicles by the offenders.

One car was held up at gunpoint with a young child inside.

Incredibly, no one was wounded.

Calin McCabe and John Tough will be sentenced in November after pleading guilty to multiple charges over the February 2015 crime spree.
