A woman in her 20s has died and three people are in hospital after a crash on the A11.

The collision happened in the early hours of Sunday morning when the group were travelling home from a Halloween event.

The black Mini One came off the road on the southbound side of the Hethersett bypass near Ketteringham and hit a tree.

An officer came across the car at around 5.15am at the junction with Station Lane.

When the car was found, one passenger was pronounced dead at the scene.

The driver, a woman in her 30s, was taken to Addenbrooke's Hospital in Cambridge in a critical condition.

The two other passengers, a woman in her 20s and a man in his 30s, were taken to hospital for further treatment but are in a stable condition.

The road was closed for more than six hours as emergency services, including two air ambulances, attended the scene.

In addition to the helicopters, a total of nine ambulances were also called out.

The crash follows another incident just three days earlier on October 31 when a cement lorry overturned on the same stretch of road.

The road was closed for more than 23 hours as crews worked through the night in an attempt to repair the damaged road surface.

In this incident, the driver also suffered injuries and was taken by ambulance to hospital.

Police are now appealing to the public for anyone who may have witnessed the crash and in particular seen the manner of driving of the Mini before the incident.

Anyone who has any information or has relevant dashcam footage is asked to contact Norfolk Police on 101 or via email at SCIU@norfolk.police.uk quoting CAD 69 of November 3.
