German singer and reality TV star Daniel Küblböck was reported missing from a cruise ship on Sunday morning after a cabin check and loudspeaker announcements.
The 33-year-old is believed to have jumped into the sea. "This is our suspicion," said a spokesman for Aida Cruises who operates the cruise from which Küblböck disappeared.
The assertion that Küblböck went overboard was supported by an eyewitness cited in Bild newspaper who said that the entertainer reportedly jumped from deck five.
Aida Cruises spokesman Hansjoerg Kunze, told Germany's DPA news agency that the ship had returned to where the incident was thought to have occurred while Canadian coast guard airplanes and helicopters took part in an intensive search for the German.
Küblböck was on holiday cruise aboard the Aidaluna ship from Hamburg to New York, according to Bild. The incident occurred about 100 nautical miles (about 185 kilometers) north of the city of St. John's on the island of Newfoundland, off the coast of Canada.
