A US man arrested after his wife went missing on a trip to the Bahamas has been released and says he will continue searching for her.

Brian Hooker was released on Monday night from Bahamian police custody where he faced questions from local officials after his wife Lynette Hooker disappeared while the pair were sailing.

"I won't be able to stop looking," he told CBS, the BBC's US partner, adding that he believed she was still alive.

Hooker has said his wife fell off their small boat along with its keys, and was swept away by currents that left him unable to reach her. He has denied any suggestion of wrongdoing.

The couple, who were travelling from Michigan, had been on a sailing trip on the evening of 4 April when Lynette Hooker went missing. The incident happened on an 8ft (2.4m) hard-bottom dinghy, and not their much larger sail boat.
