Police are renewing their appeal for anyone with information about a serious road traffic collision on the A11 this month to come forward.
A black Renault Clio and a white Vauxhall Corsa collided near to Station Lane in Ketteringham at approximately 8.30pm on Thursday, October 11.
The driver of the Vauxhall Corsa, Laura Bocking, age 21, of Aylsham, is in a stable but critical condition at the Norfolk and Norwich University Hospital. She has life-changing injuries.
The driver of the Renault Clio was uninjured and their passenger received minor injuries.
The occupants of the Renault, a man and woman aged in their 20s from Norwich, were arrested on suspicion of burglary and causing serious injury by dangerous driving. They were taken to Wymondham Police Investigation Centre for questioning, and later released under investigation.
Officers are still carrying out enquiries and have spoken to a number of witnesses but are appealing for anyone who has yet to come forward or who may have dashcam footage to contact PC Gemma Hamilton-Rout at Wymondham Roads and armed policing team on 101.
