Saskatoon City Police say the vast majority of car thefts remain preventable and are increasing. According to a 2016 survey about half of all cars stolen had the keys left inside or were left unlocked. City Police statistics for 2017 and the first three months of this year indicate that is happening in almost three-quarters of the cases. Detective Staff Sergeant A-J Chevli says it’s not unusual for stolen cars to be used in robberies, home invasions and other crimes. He also points out thieves will engage in potentially fatal high speed chases to elude police. Police also recommend removing items that would attract thieves and the club to keep them away. Chevli says many car thieves have been arrested through a joint program with SGI that places a target vehicle in high theft locations.
