Detectives have been given more time to question two men after a fatal crash which involved a 'stolen' Land Rover that was being chased by officers.

A Land Rover Defender and a Nissan Juke crashed on the A143 near the Old Harleston Road junction close to Earsham at 4.30pm on Sunday (August 13). 

A woman, who was travelling in the Nissan Juke, was pronounced dead at the scene.

At the time of the collision police officers investigating the suspected theft of a vehicle from Suffolk had been pursuing the Land Rover.

Two men, in their 20s and 40s, were arrested on suspicion of causing death by dangerous driving and were taken into custody after being discharged from hospital.

Officers applied for a warrant of further detention at Norwich Magistrates’ Court on Tuesday and were granted an additional 36 hours to question the suspects.

The incident was referred to the Independent Office for Police Conduct (IOPC) by Norfolk and Suffolk Constabularies.

A spokesman from the IOPC said: “We can confirm we have decided to independently investigate police actions prior to a fatal road traffic collision in Norfolk on Sunday afternoon.

"After being notified by Norfolk Constabulary, we sent investigators to the scene and to the police post-incident procedure to begin our enquiries.”
