The Saskatoon Police Service is asking Saskatoon residents to contact them if they find a GPS tracker on their vehicle.

Police say last September a citizen contacted them and reported he located two GPS trackers on his vehicle. Saskatoon Police say their investigation identified a suspect and a search warrant was executed at an apartment in the 2000 block of 20th Street West, where police located several more GPS trackers.

Forty-six-year-old Marty Schira, of Saskatoon, was arrested and charged with two counts each of Harassment, Mischief and Intimidation as well as a charge of Fraudulent Concealment.

Currently, six GPS trackers have been recovered by police, but they believe, based on information obtained during the course of the investigation, there are additional trackers outstanding.

The Saskatoon Police Service says the trackers are typically wrapped in black tape and placed inside the fender of the vehicle.

If you discover a GPS tracker on your vehicle, investigators ask that you do not remove or alter the device. Instead, go to police Headquarters with that vehicle and tracker intact to file a report.
