Department of Defense agents reportedly detained the wrong person in a Boston hotel room during a training exercise Tuesday night, according to FBI Boston.

The local FBI division was assisting the Pentagon in a Department of Defense training exercise at the Revere Hotel to “simulate a situation their personnel might encounter in a deployed environment.”

“Based on inaccurate information, they were mistakenly sent to the wrong room and detained an individual, not the intended role player,” the FBI Boston spokesperson added. “Thankfully nobody was injured. The Boston Police Department was called and responded to the scene to confirm that this was indeed a training exercise.”

The person who was detained might be a Delta crew member.

“Safety is always a priority of the FBI, and our law enforcement partners, and we take these incidents very seriously,” the FBI Boston spokesperson said. “The Boston Division is reviewing the incident with DOD for further action as deemed appropriate.”

A spokesperson for the Department of Defense did not immediately have a statement about the incident. The spokesperon said its initial research “has not shown any DOD exercise activity whatsoever in the Boston area.”

A Delta spokesperson said in a statement, “We are looking into reports of an alleged incident in Boston that may involve Delta people. We have nothing further to share at this time other than to reaffirm our commitment to ensuring the safety and well-being of our people.”
