The man broke away from the officers and was chased for 40 minutes, during which time he was seen to run into gardens, climbing over fences and going onto railway lines.

The man was hit by a train travelling to London Marylebone, from Aylesbury on the line near Dartmouth Road, Willesden at 5.12pm, he was pronounced dead at the scene.
