An investigation is underway following the revelation that some sort hidden camera was discovered by a female Marine in the women’s bathroom (head) aboard the USS Arlington, a San Antonio-class amphibious transport dock ship, last month. The Naval Criminal Investigative Service (NCIS) has taken the lead on the investigation, which cites a “recording device in the head” in official documents but does not specify if the camera was intended to capture images or video.

“The command has taken, and will continue to take, all necessary actions to ensure the safety and privacy of the victim,” Cdr. Kyle Raines said. “The /Marine takes all reports sexual harassment seriously, and are committed to thoroughly investigating these allegations and providing resources and care to victims sexual harassment.”

“To protect the legal rights and the privacy all involved, we cannot release details, names or any other identifying information at this time,” Raines added.

This is not the first time secret recording devices have been found aboard a U.S. ship. In 2015 it was revealed that sailors aboard the ballistic missile submarine USS Wyoming were conducting organized efforts to secretly record female sailors undressing, using cell phones and tablets that had been banned from use aboard the vessel. Over the span three months, male sailors recorded their female counterparts in the changing rooms and showers aboard the Wyoming, in some instances multiple times in the same day.
