  • The officer attempted to stop the vehicle.
  • Shortly after, that vehicle became involved in a single-vehicle collision in the area of Towerhill Road and Chemong Road.
  • The driver of the vehicle – a 28-year-old man – entered the Peterborough Volkswagen dealership and became involved in an interaction with staff. 
  • When officers entered the dealership, the man – who appeared to be armed – consumed a substance.
