Two people have been arrested in connection with a hit-and-run in Hailsham.
A member of the public discovered the victim with serious injuries on a verge on the A22 about 4.38am on Friday (21 September).
The air ambulance attended, and the 73-year-old local man was taken to Royal Sussex County Hospital in Brighton by land ambulance, where he remains in a critical condition. His next of kin have been informed.
Following enquiries, police located a white Renault – believed to have been involved in the collision – in Hellingly, which has since been seized for forensics.
A 28-year-old man and a 25-year-old woman from Hellingly have both been arrested on suspicion of causing serious injury by dangerous driving and failing to stop after a road traffic collision, and remain in police custody at this stage.
Police are still appealing for witnesses or anyone with information about the vehicle to get in touch. In particular, officers are keen to speak to anyone who was driving in the area late on Thursday (20 September) or in the early hours of Friday (21 September) who has dash cam footage.
The incident occurred just north of the Eagles roundabout on the northbound carriageway, which was closed until about 2.50pm while emergency services attended the scene.
Anyone with any information is asked to report it online or phone 101, quoting Operation Cache.
