The circumstances surrounding the incident are unknown but a Royal Caribbean spokesperson told ABC News that a guest on the ship reported seeing the guest falling overboard from a stateroom balcony at around 11pm on Friday.

"Early Saturday morning, the ship was advised by the Coast Guard that they would be assuming control of the search and the ship resumed its journey to Port Everglades, Florida," the cruise line said in a statement.

On Saturday, the Coast Guard said 946 square nautical miles had been searched so far and continued to search throughout the night.

Cruise Law News reports that passengers said there was an "Oscar, Oscar" announcement made following the incident and a helicopter arrived on the scene after an hour and a half.

Holidaymakers said conditions were very dark and difficult to rescue anyone.
