A man remains in custody after two people died in a hit-and-run crash.
The 23-year-old from Eastbourne has been arrested on suspicion of causing death by dangerous driving, driving while unfit through drink or drugs and failing to stop after a road traffic collision, Sussex Police said.
Officers were called to Bolsover Road in the East Sussex town at about 9.34pm on Friday following reports a black Seat Leon had collided with a silver Volkswagen Polo, which then collided into two parked cars - a blue BMW 330d and a grey Audi A3.
The driver of the Polo - a 48-year-old woman from Eastbourne - and the passenger - a 46-year-old man from Uckfield - were pronounced dead at the scene, police said.
Officers searched the area and arrested a man in Grand Parade at about 12.05am on Saturday morning.
Police are appealing to anyone who witnessed the collision to call 101 quoting Operation Harfield.
