Authorities in Maine say two teenagers stole a front-end loader, led police on a chase and hit two cars on a highway before officers stopped the vehicle by shooting at its tires.

Lewiston police responded to a call early Monday to assist authorities in trying to stop a bucket loader that had been reported stolen.

Police say the driver refused to stop and swerved at police cruisers several times, eventually hitting one. The officer wasn't injured.

Police say the operator drove the wrong-way on a one-way street and later deliberately struck a passenger car on the Maine Turnpike. They say an officer fired three shots at the loader's tires and the operator stopped.

Two 14-year-old boys were taken into custody. Police are still determining what charges they will face.
