A 38-year-old man has been killed in a horror M40 crash.

At 8.13pm last night police were called to the crash on the motorway between junction 2 and junction 1A southbound involving a silver BMW 5 Series and a white Man box van.

As a result of the crash, the van left the road, colliding with trees and fencing.

Tragically, the driver of the van, a 38-year-old man from Thame, died at the scene, while his passenger suffered serious injuries and was taken to the John Radcliffe Hospital in Oxford, where he remains in a serious, but stable condition.

The man's next of kin have been informed and are being supported. 

A 26-year-old man from Slough has been arrested on suspicion of causing death by dangerous driving and failing to stop at the scene of a crash. 

He is in police custody. 

Investigating officer, Sergeant Dominic Mahon, of the Serious Collisions Investigation Unit based at Bicester, said: "This collision happened when the motorway was busy with traffic, and I am appealing to anybody who may have witnessed this to contact the 24-hour non-emergency number 101, quoting URN 1406 (18/9).

"I am particularly keen to hear from anybody who may have dash-cam footage of the collision to get in touch. If you were on the motorway at the time of the collision, please check your footage and if there is anything that can assist with our investigation, please contact police.

"Sadly, the driver of the van passed away at the scene, and our thoughts are with his family at this difficult time."
