Video has emerged of suspected drug runners throwing bales of marijuana from their moving vehicle during a high-speed police chase in Arizona on Wednesday last week.

The 160-kilometre-per-hour chase was captured by a police dash cam as large packages were being hurled out of the suspects' vehicle.

The vehicle was then forced to stop with flat front tyres, leaving the suspects to flee on foot.

The footage of the chase was uploaded on the web on Sunday by the Pinal County Sheriff's office.

Approximately 170 kilograms of marijuana were retrieved following the chase and a stash house was discovered in the city of Mesa, the Pinal County Sheriff's Office said in a statement.
