A 41-year-old man is in hospital with a serious head injury after falling from a walkway at Brighton Marina.
The local man was taken by ambulance to the Royal Sussex County Hospital in the early hours of New Year's Day. Sussex Police said his condition was critical.
It is thought he fell from the walkway over the underpass running from the western end of Asda car park shortly before midnight.
Police have appealed for anyone with information to come forward.
