The U.S. Coast Guard is searching for a Canadian man who reportedly went overboard from a Royal Caribbean cruise ship headed to Puerto Rico.

Canadian Tien Phuoc Nguyen, 26, was last seen by other passengers at approximately 8:46 p.m. Saturday, the Coast Guard said in a statement released Sunday. He is reported to have jumped overboard.

The cruise ship, the Adventure of the Seas, was approximately 15 nautical miles east of Puerto Rico’s Mona Island when the incident occurred.

Nguyen was on the ship with his family, according to the Coast Guard statement. He was on the final night of a seven-day cruise with his family.

Royal Caribbean said in its own statement Sunday that as soon as the ship’s captain was alerted, the vessel was stopped, turned around, and authorities were contacted.

The location of the ship at the time of the incident was recorded by its onboard GPS system, and the incident was also captured on surveillance cameras, Royal Caribbean said.

The Coast Guard says MH-65 Dolphin helicopters and a patrol boat are being used in the search effort and the FBI is investigating why the man may have jumped overboard.

After the Coast Guard assumed responsibility for the search, the ship continued toward its final destination of San Juan, Puerto Rico.
