Mississauga, ON (21 March, 2023) ---
The province’s Special Investigations Unit is investigating the circumstances surrounding the serious injuries suffered by a 30-year-old man on the weekend in Peterborough.

Preliminary information suggests the following:
  • At approximately 2:30 a.m. on March 18, 2023, Peterborough Police Service patrol officers were made aware of a suspected vehicle theft in progress at the King Street Parkade, located at 202 King Street.
  • As officers approached, the driver of the SUV fled. 
  • When an officer – who was also a dog handler – attempted to stop the SUV in the area of King Street and Aylmer Street, the SUV and police vehicle collided. The SUV proceeded to flee southbound on Aylmer Street, and the same officer followed.
  • In the area of Morrow Park, the SUV driver went through a fence and into a construction zone. The driver fled on foot, and the officer gave chase on foot with his police dog.
  • The man was apprehended shortly after. He was taken to hospital for treatment of dog bite injuries.

Three investigators have been assigned to the case. At this time, one subject official and three witness officials have been designated.
