Saskatoon police say they've caught some car thieves who apparently didn't realize they could be tracked by GPS.

The arrest happened late Monday night after a car was taken from outside a business in the Grosvenor Park area on the east side of the city.

Inside the car was a new cell phone that had real-time GPS tracking capability, Saskatoon police said.

Although officers tried dialing the number and no one picked up, they were able to follow the signal to a neighbourhood downtown.

They found two suspects who denied they were the thieves, but they had a cell phone that displayed an unanswered call from Saskatoon police headquarters.

Police arrested the two and shortly afterwards located the stolen car, which had been abandoned nearby.

The two are to appear in court charged with stealing the car, plus a second count of theft under $5,000.
