Per protocol, a school staffer who was accompanying the students on the trip was put on administrative leave as a precaution, the spokesperson said.

"The safety and security of guests and colleagues is a top priority at Hyatt Regency Minneapolis," Mark Bastic, general manager of the Minneapolis Hyatt Regency, told KSTP in a statement. "As soon as we learned about this situation, we contacted local authorities immediately and conducted a thorough property-wide search for unauthorized recording devices; no additional devices have been found."

"Per local authorities at this time, it does not appear that anyone associated with the hotel was involved," the statement continued. "The hotel continues to fully cooperate with Minneapolis Police Department on their investigation."
