An extensive search is being carried out in Lowestoft following reports of a man in trouble in the sea.
The incident was called in by a paramedic who thought he saw a person in the water just off South Beach who appeared to wave and then disappear.
Three RNLI lifeboats, one from Lowestoft and two from Gorleston are currently searching, along with Coastguard Rescue Teams from Lowestoft, Southwold and Gorleston. Lifeguards from Lowestoft are also searching along with Suffolk Police.
Also involved is the HM Coastguard search and rescue helicopter from Lydd.
Rob Priestley, controller for UK Coastguard said: 'We received initial reports that a man had been seen struggling in the water. We launched the search which is currently covering an area across Lowestoft. If anyone has any information that this man got ashore safely or if it was you, please call 999 and ask for the Coastguard. Let us know you're safe.'
The incident was called in just before 1pm.
A Lowestoft lifeboat spokesman said the Gorleston lifeboat had been searching the area known as children's corner, while the coastguard was concentrating on the rocks by South Beach.
He said: 'The helicopter has be over and done a thorough search.
'The search seems to be more between Lowestoft and Gorleston now because the tide would be taking anyone in the water that way to the north.'
The East of England Ambulance Service also sent an ambulance crew, ambulance officer, rapid response vehicle and Suffolk Accident Rescue Service team to the scene off Marine Parade.
