A 20-year-old woman is in a serious but stable condition after a collision in Rainham Road on Monday.

Police are appealing for information after a burnt out Smart car, believed to have been stolen, was found in Askith Road, Rainham following the crash.

Just after 3am police were called to reports a silver Smart Car had rolled and righted itself on the road.

A witness has reported that a male carried an injured woman to another vehicle and asked the driver to call ambulance.

It is alleged the man then left the scene.

The woman had multiple injuries and was taken to an east London hospital by London Ambulance Service. She is undergoing surgery and her condition has been described as serious but stable.

Police believe the Smart car was using false plates and had been reported lost or stolen from the Hornchurch area on March 17.

They are appealing for witnesses to the collision or for anyone who may know of someone who owned or drove a silver Smart car that now no longer has it to come forward.

The collision is being investigated by the Serious Collision Investigation Unit at Chadwell Heath.

Anyone with information is asked to call the unit on 0208 5974874, the police non-emergency line on 101 or Crimestoppers on 0800 111 555.

No arrests have been made.
