A U.S. traveler was arrested and fined in the Bahamas for bringing a gun on a cruise ship.

Police boarded the vessel at Prince George Wharf in Nassau on Dec. 2, where they apprehended a 69-year-old woman after she was “found in possession of a firearm and ammunition,” the Royal Bahamas Police Force said in a Dec. 3 crime report.

The woman’s granddaughter identified her as Mary Robinson on a GoFundMe page established to raise funds to pay the fine.

“She went on a cruise for her adopted son Johnny's 12th birthday,” Graci Exendine wrote on the page. “She is 69 years old and on her trips she usually (brings) some kind of protection but usually leaves it in the car since you aren’t allowed to bring it on the ship. Well accidentally she didn’t leave it and it was found in her bag when they checked at the Bahamas and she was arrested.”

Exendine did not immediately respond to a request for comment.

Bjorn Ferguson, an attorney representing Robinson, said she pleaded guilty and was fined $8,000. “In default she would have (had to spend) 24 months at the Bahamas Department of Corrections,” he told USA TODAY in an email. “The fine was paid.”

Robinson was sailing on Royal Caribbean International’s Liberty of the Seas at the time, Ferguson said. The ship departed from Florida’s Port Everglades on Dec. 1, according to CruiseMapper.

Firearms and other weapons are prohibited on Royal Caribbean ships, per its website.

Port Everglades referred USA TODAY’s request for comment to Royal Caribbean. The line’s parent company, Royal Caribbean Group, did not immediately respond to a separate request for comment.
