TORONTO - Ontario's police watchdog has cleared a Toronto officer who shot and injured a man he believed was reaching for a gun.

The Special Invetigations Unit says it happened after police stopped a car by driving into its passenger door.

Police followed the car after its occupants were seen leaving a commercial building with a box late on Aug. 6 or early on Aug. 7.

The SIU says the car slid off the road on Conroy Avenue, and the officer fired a shot when he saw the driver reach for something he believed was a gun.

The SIU says no gun was found in the car but investigators located a police scanner and a cellphone.

Director Ian Scott says he believes the officer was justified in firing his gun and did not commit a criminal offence.
