Coastguard teams, two lifeboats and a rescue helicopter are searching the north Cornwall coast for a missing man.
Mark Neville, 45, disappeared from his home in Newquay on Thursday night.
Police said they were becoming increasingly concerned for his welfare and have urged anyone with information to come forward.
Mr Neville is described as 6ft 4in (1.6m), of thin build, with short light brown hair. He was believed to be wearing jeans and a green top.
Maritime and Coastguard Agency spokesman Richard Williams said emergency services, including a helicopter from RNAS Culdrose, had been searching an area from Kelsey Head, near Crantock, to Watergate Bay.
