A 17-year-old girl was hospitalised with serious injuries following a crash just north of Brighton last week.
Police are now seeking witnesses to the crash at the junction of Saddlescombe Road with Devil’s Dyke Road, near Poynings.
It happened at around 6.30pm on Thursday (February 23), and involved a blue Renault Clio and a silver Nissan Qashqai.
The 17-year-old girl from Hurstpierpoint, who was a passenger in the Renault, sustained serious leg and pelvic injuries. Police said her injuries are not thought to be life-changing or life-threatening.
She was released from the car by firefighters and taken by ambulance to the Royal Sussex County Hospital, Brighton, where she has been detained for treatment.
The Renault driver, a 17-year-old boy from Sayers Common, sustained a cut to his forehead.
The Nissan was driven by a 35-year-old woman from Henfield who was unhurt. Her passenger, her six-year-old daughter, sustained bruising.
Saddlescombe Road was closed until almost 1am between the Beggars Lane roundabout and Devil’s Dyke Road while the incident was dealt with.
PC Sarah Harman, of the Polegate road policing unit, said: “We would like to thank drivers whose journeys were disrupted by the closure and diversions for their patience and understanding.”
Anyone who saw what happened or who noticed either vehicle being driven just prior to the crash is asked to report details online here, quoting Operation Harrier.
