A woman has died after a second minibus crash on the M4.
Police were called to the westbound carriageway between junction 14 and 15 by Membury Services, near Hungerford in Berkshire, just before 11.30am on Saturday after the vehicle overturned.
The woman was airlifted to hospital in Oxford where she later died, police said.
Three others on the minibus were taken to hospital in Swindon but only suffered minor injuries.
Investigating officer Pc James Baker, of Thames Valley Police roads policing unit, appealed for anyone who witnessed the incident to come forward, adding: ‘This is another tragic incident on our roads, and our thoughts are with all those who have been affected.’
The crash comes just three days after a minibus crash left three people dead on Thursday.
The minibus had been carrying staff and children from an autism school when it collided with a lorry on a nearby stretch of the motorway between junction 14 and 13 by Chieveley at around 12.20pm on Thursday.
Two staff members from the Prior’s Court Foundation died at the scene and another, who was driving the minibus, died in hospital on Friday.
Six others, including the lorry driver, were taken to hospital and three are still being treated.
