More casualty details emerge in M5 quadruple fatality

Further details have emerged following Saturday's crash on the M5, which claimed four lives.

The motorway in South Gloucestershire was shut after a van travelling south crashed through barriers and collided with two vehicles heading northwards.

Police said one of the victims was travelling in a Seat Leon and three others in a second car, the details of which cannot yet be released.

Three others remain "critical but stable" in hospital.

They are a 42-year-old woman, a 12-year-old boy and a 10-year-old girl.

"A full investigation is being carried out into the circumstances of this collision, which involved a Mercedes box van and two cars," an Avon and Somerset Police spokesman said.

"Our thoughts remain with the families of all the victims of this tragic incident.

"[The] investigation will involve a thorough examination of all the vehicles involved and we're working closely with the Driver and Vehicle Standards Agency (DVSA) to progress these enquiries," the force spokesman added.

The van driver, a man in his 40s from Worcestershire, has been spoken to by collision investigators.
