A search is underway for a passenger who fell off a Royal Caribbean ship in Singapore. 'My mother could not swim,' the passenger's son said.

• A passenger on Royal Caribbean's Spectrum of the Seas fell overboard into the Singapore Strait.
• Local authorities in Singapore were notified on Monday and a search is underway.

A passenger on Royal Caribbean's Spectrum of the Seas fell overboard on Monday, the cruise company confirmed to Insider.

According to the Singapore-based news outlet, The Straits Times, the passenger is 64-year-old Reeta Sahani, who was traveling with her husband Jakesh Sahani.

The couple was in the Singapore Strait on the last day of their four-day cruise to Malaysia when she fell.

According to The Straits Times, Jakesh woke up in the middle of the night and discovered his wife was not in their cruise cabin.

He notified the ship's officials, who, according to The Straits Times, told him that his wife was seen on the ship's CCTV footage sitting on the ship's railing at about 4 a.m.

Additionally, the ship's overboard detection system alerted that something or someone had fallen overboard the ship, the news outlet reported.

In a statement sent to Insider, a Royal Caribbean spokesperson said that "the ship and crew immediately reported the incident to local authorities and launched a search and rescue operation."

"The shipboard team is working with local authorities and our Care team is now offering assistance and support to the family," the statement continued.

In a news release, the Maritime and Port Authority of Singapore said it was alerted of the overboard passenger at 7:50 a.m. local time on Monday.

The Maritime and Port Authority of Singapore did not immediately respond to Insider's requests for comment.

Speaking to The Straits Times, Reeta's son Apoorv Sahani said his mother did not know how to swim.

"She was on a holiday enjoying herself and then this whole thing happened. It doesn't make sense," Apoorv, who was not onboard the Spectrum of the Seas, said.

"We've asked to see the CCTV footage, but so far we've not received anything yet for us to confirm that it was her," he told the news outlet. "All we know is that the ship's crew thinks she jumped."

Since the start of 2023, there have been 12 people who have fallen off cruise ships, according to data compiled by Ross Klein, a social work professor at Memorial University of Newfoundland, who runs a cruise safety website.
