A 14-year-old girl has been taken to hospital with head and chest injuries following a hit-and-run car crash on the A22 Hailsham bypass.
A red Nissan Micra collided with a silver Honda Civic around 5.40pm on Saturday (March, 10) which caused the Nissan to spin into the central reservation.
Police said the Honda is also thought to have spun, before it drove in the wrong direction, and then headed off along the A295 South Road.
The teenage girl was in the Nissan, and was taken to Eastbourne DGH, while an 11-year-old girl also in the car had whiplash.
It was being driven by a 35-year-old woman from Eastbourne, who suffered bruising.
Police now want to speak to the driver of the Honda, a man who officers said may have a beard.
The Honda is believed to have sustained frontal damage.
Anyone with information about the incident is asked to contact police online here, or phone 101, quoting reference number 930 of 10/03.
