Detectives in London are appealing for witnesses following a fatal collision involving several vehicles.
Police were called just before 7.00am on Monday, December 11th to Norwood Road amid reports a woman was injured.
The female pedestrian, who is believed to be aged in her late 20s or early 30s, was treated at the scene but pronounced dead a short time later.
Officers say the woman was struck by a HGV as she crossed the road at a pedestrian crossing. The driver failed to stop at the scene.
Police also believe she was then hit by a second lorry and two cars - and that none of these drivers stopped either.
Police say formal identification is yet to take place and enquiries to trace her next of kin are ongoing.
Acting Detective Sergeant Alastair Middleton says: "I am appealing for anyone who witnessed the collision and the moments afterwards to contact us.
"I would also urge the drivers of all four vehicles to come forward and speak with my team."
