A young woman is in hospital with a broken pelvis, broken vertebrae in her neck, tissue damage and bruising after being knocked down on a pedestrian crossing in Sheffield by two cars which failed to stop.
The 21-year-old was using a crossing outside Marks and Spencer on Ecclesall Road when two vehicles approached the red traffic light, overtook the line of stationary vehicles at the lights, and smashed into the woman as she crossed.
She was flung around 20m down the road before falling to the ground.
Both vehicles failed to stop at the scene.
Police especially want to talk to the owner of a bulk tipping HGV which was one of the stationary vehicles at the red light, as its driver may hold vital information that could identify the culprits.
The woman is a university student, originally from Ossett near Wakefield.
Anyone who witnessed the collision at 10pm on Wednesday, or who knows of a vehicle that has sustained damage, is urged to call police on 101 quoting incident 1,221 of May 8.
