A 78-year-old man has died in a crash on the M25 after suffering a suspected medical episode at the wheel.

At around 8.55am this morning (September 4), a Mercedes Benz coach veered across three lanes of the motorway before hitting the central reservation and coming to a stop on the hard shoulder near junction 14 for the M4.

The coach driver sadly died at the scene despite the efforts of South Central Ambulance Service.

Six passengers on the coach, four women in their late teens and two teenage girls, suffered minor injuries but did not require hospital treatment.

Thames Valley Police is appealing for witnesses to a fatal road traffic collision.

Investigating officer PC Jonathan Housby, of the Joint Operations Roads Policing Unit, said: “Firstly, our thoughts are with the man’s loved ones and everyone else involved in this road traffic collision.

“It is thought to have been caused by a medical episode and is not being treated as suspicious at this time.

“I am appealing for any witnesses to this incident to please come forward.

“I’d also ask anyone with a dash-cam who was in the area just prior to or at the time of the collision to check any footage in case it has captured something that could help our investigation.

“You can make a report online, or by calling 101, quoting reference 43220397531.

“Alternatively, contact independent charity Crimestoppers anonymously by calling 0800 555 111 or via its website.”
