No further searches will be made for a missing man reportedly heard shouting for help from the sea unless fresh sightings of him are made, coastguards have said.
An air and sea search was launched just before 2.45pm yesterday after a person in trouble near Black Rock Station in Brighton.
Some clothes were found on the beach although it was unclear whether they were connected to the missing person, Sussex Police said.
Intensive efforts involving coastguard rescue teams, RNLI crews and other emergency staff failed to find the man.
As darkness fell yesterday, the search operation was scaled back and the area where the man was last seen was monitored overnight.
"As it's a missing person, it's now in the hands of the police. If we receive any additional information or any fresh sightings then the search will resume."
A search by coastguards, lifeboat and police after a man was reported to be in the sea by Brighton Marina Yacht Club on Wednesday afternoon was stood down at dusk.
