Toronto police are requesting help from witnesses after a hit-and-run in Scarborough Monday night left a woman trapped beneath the car with serious but non-life threatening injuries.

The incident happened at 8:40 p.m. at Eglinton Avenue East and Midland Avenue.

The 44-year-old woman and her 11-year-old son were crossing Eglinton, walking north to south on the west side of the intersection, when she was struck by a 1999 Lincoln Navigator heading north on Midland Avenue and turning left into the westbound lanes on Eglinton.
