A 23-year-old has died after a car lost control and overturned in a late night horror smash.
The young Slough woman was one of five people in a blue Volkswagen Golf which mounted a roundabout and rolled onto its roof at about 2.30am in Chalfont St Peter.
Detectives closed the A413 between A40 Oxford Road and The Greyhound Inn (Joiners Lane Roundabout) for more than 10 hours as they investigated the deadly smash.
It was reopened at midday.
Early reports indicate the car was being driven south on the A413 Amersham Road, before losing control at the roundabout junction with Kingsway.
Having mounted the roundabout and rolling the car, the 23-year-old woman was tragically pronounced dead at the scene after succumbing to her injuries.
Three other passengers were taken to hospital with another person suffering minor injuries not requiring hospital treatment.
One of the injured people remains in St Mary’s Hospital in London with serious injuries, while the other two have since been discharged.
