Salt Lake police are investigating a series of vehicle thefts in which the autos were stolen by someone punching out ignitions and driving away the cars.

Detective Harley Kinser said more than a dozen vehicles have been reported stolen, apparently by someone using a slide hammer to punch out the ignition.In the cases the Salt Lake police are investigating, Kinser said the thieves generally have broken the window to get into the vehicle. Cars in parking lots, street-side parking areas and driveways have been broken into and stolen.

Installing alarms in vehicles will deter thieves, he said. And it still is sound advice to lock vehicles.
