A vehicle being pursued by Peel Regional Police officers drove onto a sidewalk and struck a pedestrian in Mississauga Monday night, according to the province’s Special Investigations Unit.

The SIU, which is the provincial body that looks into serious incidents involving police, said the 46-year-old man who was struck was taken to St. Michael’s Hospital with head injuries, internal injuries and a fractured leg.

The SIU is now investigating exactly what happened during the collision, which occurred around 8 p.m. near Hurontario Street and Burnhamthorpe Road.

In a release, the SIU said that officers were conducting an investigation on Absolute Drive at the time of the incident.

Officers attempted to make an arrest when the driver manoeuvred the vehicle onto the sidewalk and hit the pedestrian.

The driver then fled the scene.

Witnesses at the scene told CP24 that they saw a police chase prior to the collision, which may have involved both marked and unmarked police cars.

The ambulance containing the pedestrian was escorted to hospital by police cars.

The SIU said it has assigned seven investigators to look into the circumstances surrounding the incident.

Depending on the evidence, the SIU can lay charges against the officers involved in the incident, or clear them of any wrongdoing.
