A man has been left with life-changing injuries after a car came off a motorway and ended up on its roof in a field last night.

At around 9.25pm on Sunday night, a blue Ford Focus was travelling north on the M40 between junction 2 and junction 3, near Beaconsfield, when it left the carriageway and drove up the adjacent embankment, through a hedge.

The car ended up on its roof in a nearby field and the passenger, a 35-year-old man, was seriously hurt and taken to Wexham Park Hospital.

The driver, 27, who was also injured but has since been released from hospital, has been arrested on suspicion of causing serious injury by dangerous driving and is currently in custody.

Thames Valley Police now want to speak to anyone who may have seen the crash or the blue Ford Focus driving in the area around that time.

Anyone with information should call 101 and ask to speak to PC John Belson of the Amersham Roads Policing Team.

To give information anonymously, call Crimestoppers on 0800 555 111.

No personal details are taken, information is not traced or recorded and you will not go to court.
