Arron Hough, 20, disappeared from the Harmony of the Seas some 267 miles off Puerto Rico about 4am just after posting a cryptic tweet on his twitter page.
His last Tweet has since been revealed, with the young man writing:
“Beneath the water is beauty.. Always look beneath the surface before you decide on things”.
The young man’s disappearance has sparked a huge search, with a HC-130 Hercules airplane crew from Clearwater and the crew of the Coast Guard Cutter Resolute called in.
The cruise ship was off Aguadilla, Puerto Rico at the time Arron disappeared and is based Port Everglades in Fort Lauderdale.
Arron, from Sunderland, was a cast member of the musical “Grease” which was being performed onboard the ship.
He only began working for Royal Caribbean this year after graduating from the Urdang Academy theatre school in London.
The Urdang Academy tweeted:
“We are all praying for @Arronhoughxox and his family. Please keep up your hope and faith that he is found safe and sound as soon as possible.”
Royal Caribbean International said a member of the entertainment team onboard the Harmony of the Seas ship did not report to work as scheduled on 25 December.
They said in a statement;
“We are saddened to report that after a review of the ship’s closed-circuit camera footage, he was observed entering an area on Deck 5 at around 4am and was not seen again.”
