Missing Brighton swimmer search called off
No further searches will be made for a missing man heard shouting for help from the sea unless fresh sightings of him are made, coastguards have said.
A member of the public called 999 after hearing the man shouting for help near the Western Arm of Brighton Marina, just before 14:45 BST on Wednesday.
The RNLI lifeboat was dispatched but the man had disappeared under water.
Emergency services spent the afternoon searching the scene but scaled it down as darkness fell.
Some clothes were found on the beach although it was unclear whether they were connected to the missing person, Sussex Police said.
The Maritime and Coastguard Agency (MCA) initially said the search would resume at first light.
But a spokesman said it was now a missing person inquiry being handled by police.
"If we receive any additional information or any fresh sightings then the search will resume," he said.
