Teen's body found in Mississauga

The body of a teenaged girl has been found in a parkette in Mississauga.

Peel Regional police say the body was discovered just after noon in the parkette at Spinnaker Circle, which is near Highway 401 and Mavis Road.

Police say they are treating the incident as a suspicious death, but have not released any further details.

Police have not determined if the death is connected to another incident Friday that shut down the westbound lanes of Highway 401 for more than four hours.

The highway was closed from Hurontario Street to Mavis Road after a teenaged boy plunged to the road from the Mavis overpass and was struck by a car. He was airlifted to hospital and is in serious condition.
