A Thunder Bay police cruiser was involved in a collision Friday night on the city's south side.

The cruiser was travelling south on Waterloo Street N., when it collided with a Subaru sedan at the intersection with Victoria Avenue E., according to a police statement.

Two police officers in the cruiser sustained minor injuries, as did the driver of the sedan. Both vehicles sustained "significant" damage, according to the release.

Police credit the deployment of airbags and the use of seatbelts for lessening the severity of the injuries suffered.

Police were en route to robbery

At the time of the crash, he cruiser had been on its way to a suspected robbery at a Mac's convenience store on Syndicate Avenue South.

In that incident, a clerk noticed an unpaid item in the pocket of a female customer. When the clerk challenged her, the woman said she had a weapon and fled the store.

Police describe the suspect as in her mid-20s, five feet seven inches tall with a thin build and dark hair. She was wearing a black, hooded parka, faded jeans and sunglasses at the time of the incident.
