what was he doing on the tube at 5.03 am?
British Transport Police officers were called to the line near Wimbledon Park London Underground station. A statement said: "The incident was reported to BTP at 5.03am and was also attended by Metropolitan Police officers. London Ambulance Service medics attended but the man, believed to be 23 years old, was pronounced dead at the scene. The incident is currently being treated as non-suspicious."
It is believed Maynard may have been trying to escape police shortly before his death.
Officers tried to pull over a black Mercedes, which was being driven 'erratically', an hour before Maynard's body was found on the tracks.
A Metropolitan Police spokesman said: 'At approx 4.15am on Monday, 18 June, officers stopped a vehicle after it was seen being driven erratically in Arthur Road, SW19.
'The male driver of the vehicle - a black Mercedes C250 - made off on foot. Officers were unable to locate the man.
'At approx 5.10am the body of a man fitting the same description was found on tracks near Wimbledon Park station.'
The force added that it was still trying to identify the man found on the tracks and that the Directorate of Professional Standards and the Independent Police Complaints Commission (IPCC) have been informed.
England were practising at Maynard’s home ground of the Kia Oval ahead of Tuesday’s second one-day international when the news began to emerge. The players are said to be in shock.
