Three teens have been charged in connection with a series of mischief incidents, including allegedly throwing rocks at parked vehicles that smashed windows. Police say the incidents happened on several streets in Gravenhurst early Wednesday morning, damaging a total of 10 vehicles. The young people who’ve been arrested are a 14-year-old, 16-year-old and 17-year-old, all from Port Sydney and each charged with 10 counts of mischief. They will appear in court at a later date. Investigators are still asking for anyone with information about the incidents or who may have video surveillance footage to come forward to Bracebridge OPP. The investigation continues.
