The U.S. Coast Guard are searching for a woman who went overboard at a Mad Decent Boat Party on Thursday night (November 12), Billboard reports.

According to a statement from Norwegian Cruise Lines, the woman was seen “intentionally going overboard while the ship was sailing the Yucatan Channel.”

“The ship’s crew immediately initiated rescue measures, including deploying three rescue boats and notifying the Coast Guard and other relevant authorities,” the statement continues. “The search for the guest is ongoing. Both the ship and charter company teams are providing support to the family and all impacted guests during this difficult time.”

According to YourEDM, the stages were temporarily closed after the alarm was raised and all passengers asked to return to their rooms for a headcount.
