PRINCE FREDERICK --- Calvert Sheriff's officers report that GPS units in place in parked cars at area restaurants and stores have become popular with local thieves and crackheads, who find they can turn your pricey road maps into quick cash. 

Police report that between 7:00 p.m. and 10:30 p.m. on Friday, February 29, deputies responded to four calls in Prince Frederick for damaged property and theft. 

Four victims had each had a window in their vehicle smashed in and various navigational systems stolen. 

 One victim had been parked outside of Stoney’s Restaurant, 2 had been parked at the Walmart and another victim had been parked outside of the Mamma Lucia’s Restaurant. 

At least two of the navigation systems are reported to be Garmin GPS’s valued at $250 each.  Anyone with information is asked to contact Det./Sgt. Michael Moore of the CIT at 410-535-2800 extension 2454.
