Calgary police officer injured while conducting traffic stop

CALGARY - A Calgary police officer had to be taken to hospital after he was injured while making a traffic stop.

Police say the officer's vehicle was rear-ended by a tractor-trailer unit hauling livestock on Deerfoot Trail, a freeway that runs north-south through the city.

The officer's injuries were not serious, although the collision caused extensive damage to the vehicles.

Police say a second person, an occupant from the vehicle originally stopped by the officer, also had minor injuries.

Traffic had to be diverted for a time while investigators were on the scene.

Police say there are no indications at this time if alcohol or speed were factors.
