The province’s Special Investigations Unit (SIU) is investigating the circumstances surrounding the death of an 18-year-old at Square One Shopping Centre in Mississauga on Wednesday.
Peel Regional Police officers were called about a person in distress who was heading to the mall near Highway 403 and Hurontario Street.
At around 2:20 p.m., an officer spotted the teen in the mall’s parking garage.
A short time later, the teen fell from the garage to the ground below. He was later pronounced dead at the scene.
The SIU was notified because an officer was present at the scene at the time of the fatal fall.
No further details about what transpired have been released. The agency is asking witnesses to come forward if they have any information or footage related to the incident.
The SIU is an independent government agency that investigates the conduct of police, among other officials, that may have resulted in death, serious injury, sexual assault and/or the discharge of a firearm at a person.
