Officers tried to stop a vehicle near Shepherd's Bush before it crashed into a car just after 8.30pm on Monday.

Several people in the pursued vehicle fled on foot.

The man who died, who has not been named, was seen close to the tracks near East Acton station before being hit by the passing train.

Detectives are still trying to determine his identity so his family can be informed.

A cordon in place at the scene was lifted at about 1pm on Tuesday.

Mike Hill, who lives near the scene, said: "We just heard fire engines, the ambulance and police cars.

"We saw the car get towed away. All the air bags had gone and the back wheel was missing.

"They were all searching the railway lines last night and there were no trains until this morning."

A man who was in the car that was crashed into was taken to hospital as a precaution.

An investigation is ongoing, and the Metropolitan Police said its Directorate of Professional Standards has been informed.
