Police are searching for a motorcyclist and his bike after an elderly man suffered seriously injured in a crash in Hammersmith , where the rider involved failed to stop.
Met Police officers were called to reports of a collision involving a motorbike and pedestrian in Fulham Palace Road at 4.45pm on Monday, May 21.
The pedestrian, a man in his 80s, was crossing the road when he collided with the side of the motorbike.
A Met Police spokesman said the motorcyclist had been filtering down the offside of a line of traffic when the crash happened.
Witnesses reported the rider appeared to be aware that he had collided with the pedestrian but instead of stopping he rode off, turning down Greyhound Road, the spokesman added.
The Met Police have called the incident a "fail to stop collision".
London Ambulance Service attended and the elderly man was taken to hospital where he remains - while his condition is not life threatening he remains in a serious condition.
His next of kin are aware.

The rider of the motorbike was described as a man, wearing black and white motorcycle clothing.
There have been no arrests in the investigation.
