A teacher from Nottingham has been swept out to sea in Bulgaria.
It is believed Ethan McKen, 24, was at a beach in Burgas when he and a friend were hit by a wave.
Mr McKen was unable to get back to shore and his friends were unable to reach him, a family member told the BBC.
Travel agent Thomas Cook is working with local authorities to find him. The foreign office has been made aware of the incident.
