A 28-year-old man was attacked after a night out in Brighton.
The victim got into a cab at the taxi rank at the bottom of West Street in Brighton between 3am and 4am on Sunday (24 February).
Four men were already in the taxi which then headed east along the A259 coast road.
It stopped just before the Smugglers Rest pub in Peacehaven, Sussex Police said.
The victim, who lives in Newhaven, said that he was dragged from the taxi and attacked by the other four passengers.
