An elderly man who was airlifted to hospital is no longer thought to have life threatening injuries.
Emergency services were called to the scene at Ashford Road at 12.46pm on Tuesday (December 11) where a man and a woman, both pedestrians in their 80s, had been involved in the collision.
The man was airlifted to the Royal Sussex County Hospital in Brighton with potentially life threatening injuries. Police later announced his injuries were serious but not life threatening. The woman was taken to Eastbourne DGH with serious injuries, also not thought to be life threatening.
A third person, a middle-aged man, who is believed also to have been a pedestrian, was taken to the Eastbourne DGH for treatment for shock.
A Yamaha motorbike had been abandoned at the location and the rider had run off from the area.
Inspector Phil Duffy, from the Sussex Police Road Policing Unit at Polegate, said, “We have had to close roads in the area around Ashford Road to facilitate the landing of the air ambulance and for rescue and investigation work to take place.
“I should like to thank drivers and the general public for their co-operation and understanding while we deal with this very serious incident and ask they try to avoid the area for the next few hours.”
Anyone who witnessed the collision or who saw the bike being ridden in the area in the time leading up to the incident is asked to call Sussex Police on 101 quoting Operation Barnhill. Alternatively, email firstname.lastname@example.org.
