THE DRIVER of a BMW involved in yesterday's M4 crash has died.

The 66-year-old was driving a black BMW 520D, which hit the central reservation of the M4 between junctions 16 and 17 at around 3.40pm on Friday.

He was taken to Bristol Royal Infirmary by air ambulance but later died, police said today.

Police, Highways England, South Western Ambulance Service, the Great Western Air Ambulance and fire crews from Swindon and Westlea all attended the scene.

The crash caused long delays for Friday commuters, with sections of the M4 westbound shut by police investigators for up to four hours.

Police have appealed for drivers who may have seen the crash to come forward.

PC Alan King said: “Police are keen to trace any witnesses to the incident and any persons who may have been travelling on the eastbound carriageway who have dashcams which may have captured the collision.”

Anyone with information should contact Tri-Force on 101 or anonymously, via Crimestoppers, on 0800 555 111.
