The FBI is investigating sexual assault allegations on a Carnival cruise ship.

An FBI spokesperson told KHOU 11 that the alleged sexual assault incident took place onboard the Carnival Breeze ship based out of Galveston, Texas. The incident happened on a cruise that returned to Galveston on Monday.

“FBI Houston is aware of allegations of a sexual assault that occurred on the Carnival Breeze cruise ship which docked in Galveston on 07/28/2025,” the FBI spokesperson wrote. “As is customary with crimes aboard a cruise ship, an FBI Maritime Liaison Agent, based out of the Texas City Resident Agency, is coordinating with the U.S. Coast Guard (USCG), Customs and Border Protection (CBP), and the cruise line regarding this incident. Also keeping in line with case reviews or open investigations, the FBI will not be providing additional details or updates regarding these matters.”

The Carnival Breeze cruise was 4 days and made a stop in Cozumel, Mexico.

“This routine protocol ensures transparency. It does not automatically imply suspicious circumstances, and the facts of this matter do not suggest any such activity. We extend our heartfelt sympathy to our guest’s family and loved ones in this difficult time,” the spokesperson added.
