Alberta's police watchdog is investigating after a Lethbridge officer drove over an injured deer multiple times with his vehicle to try and kill the animal.

Lethbridge Police Service said in a release Tuesday that it was contacted Monday by a local media agency that had obtained a video of an on-duty officer using a police truck to drive over the animal along the 1600 block of Scenic Drive South.

Chief Rob Davis reviewed the video, then notified the director of law enforcement and triggered an Alberta Serious Incident Response Team (ASIRT) investigation.
