Providing an update just before 6 a.m., investigators said two vehicles on the westbound 401 were involved in a shooting incident around 1:30 or 1:40 that same morning.

The suspect vehicle is described as a dark sedan. OPP said the victim’s vehicle, a Red Hyundai, was found to have bullet holes on it’s driver’s side.

Two occupants were in the targeted vehicle at the time of the shooting, though no injuries have been reported.

Anyone that may have witnessed the interaction is asked to contact Cambridge OPP at 519-654-0150. Dash camera footage is also being collected.
