A motorcyclist is in hospital with serious injuries following a suspected hit and run.

The 18-year-old was riding a bike which was involved in a collision with a car last night.

Officers were called to the scene in Court Road, Orpington just before 8pm.

Paramedics from the London Ambulance Service and the London Air Ambulance were also in attendance.

The teenager was taken to a south London hospital where he remains in a serious condition.

Just before midnight, police attended a nearby address where they arrested a woman on suspicion of failing to stop at the scene of a collision and failing to provide a specimen of breath for analysis.

An investigation is under way, led by the Serious Collision Investigations Unit.

They are appealing for anyone who witnessed the incident and who has not yet spoken to police, or anyone who has relevant dash cam footage, to call 0208 285 1574, providing the reference 6500/30APR.
