There was likely a group of very unhappy car owners in Saskatoon Friday. Just before one in the morning police received a slew of calls from residents in the 600-900 blocks of Avenues I, K and L South. They reported hearing glass breaking and saw a suspicious vehicle in the area. Police arriving on the scene quickly learned that seven vehicles in the area had windows broken. Officers pulled over a vehicle matching the description and took a 19-year-old and a 17-year-old into custody. The teens are now facing a string of mischief charges. Anyone whose vehicle was damaged last night is asked to report it to Saskatoon police.
