A search is under way for a man who fell off a boat in Dorset in the early hours of Monday morning.
The Maritime Coastguard Agency said it received a call at 2.15am about an unidentified person in the water at Poole Harbour.
Dorset Police later named the man as 24-year-old David Haw and urged the public to get in touch if they had any information.
Mr Haw has been described as white, around 5ft 10in, with a short beard and mousey brown hair that is shaved at the sides and back.
Coastguard rescue teams, a search and rescue helicopter and two RNLI lifeboats have all been working alongside police to look for him.
“A coordinated multiagency search and rescue effort has been going on since the initial report of David’s disappearance,” Chief Inspector Darren Harris said.
“We will continue with our efforts to find David.”
The incident happened on the final day of the biannual Poole Regatta, which was forced to suspend yacht racing while inquiries were carried out.
It announced on its website that its prize-giving ceremony has also been cancelled.
