Passengers were awakened early Friday on the 'Allure of the Seas' Atlantis Caribbean cruise and told to assemble for an emergency count because a man was reportedly overboard off the Mexican coast, KABC Los Angeles reports:

"An ABC7 photographer aboard the Royal Caribbean cruise charter said passengers were awakened Friday morning by an emergency announcement, saying a man was believed to be overboard. The ship's captain confirmed the incident to passengers and said all rescue attempts are being made. An emergency assembly was called so passengers could be counted. The ship was on its way back to port in Fort Lauderdale, Fla. It stopped Friday off-shore near Cozumel, Mexico."

Twitter user @DarienneLake tweeted about the incident: "there was an announcement for someone to contact services at 6:30am, then at 7am we went to muster stations to be accounted…at 9am we were allowed back to our rooms. They have search boats looking for glitter in the water. Currently in Cozumel."

UPDATE: UK Telegraph reports on a statement from Royal Caribbean:

"A guest on-board the ship saw the man fall overboard at 12.10pm (7.10am local time) on Friday. The ship made multiple public announcements and began a complete search of the ship, in efforts to locate the guest. When the guest did not respond to the pages and was not found on-board, the captain alerted the local authorities of the situation.

A review of the ship's closed-circuit camera footage observed the 30-year-old British male guest going over the balcony railing in his stateroom on deck 11. The location of the ship at the time the guest went overboard was marked on the ship's Global Positioning System (GPS) and the US and Mexican coastguard were alerted.

Allure of the Seas, along with Mexican coastguard, Mexican navy and the pilot boat, conducted a search for the missing guest…Our care team is providing support to the guest's family and our thoughts and prayers are with them."

The man's name has not been released.
