51-year-old man missing after going overboard during Caribbean ...

A 51-year-old man went overboard from a Norwegian cruise ship Thursday during a trip to the Caribbean, and, despite an extensive search, he has not been found.

Norwegian Cruise Line said the man was reported to have fallen off the ship around 3 p.m., while it was sailing from Ocho Rios, Jamaica, to Nassau, Bahamas.

"The authorities were immediately notified, and a search and rescue operation under the guidance and oversight of the Bahamas Rescue Coordination Center went underway," the cruise line said in a statement.

The search was unsuccessful, and the ship was allowed to continue on its journey, according to the cruise line. Norwegian did not share any information on the circumstances of the man's fall or provide additional details about the search.

The Royal Bahamas Defense Force did not immediately respond to a request for comment.

It's not clear if the search for the man will be resumed.

The man, who has not been publicly identified, was traveling with a large group of people, including relatives, who Norwegian said were receiving support.

"Our thoughts and prayers are with his loved ones during this difficult time," Norwegian Cruise Line said.
