DENVER -- An unruly passenger aboard a Southwest Airlines flight from Chicago to Salt Lake City forced the pilots to make an unscheduled landing in Denver.
Southwest Airlines spokesman Chris Mainz said the pilots aboard Flight 3655 declared an emergency Monday night and landed at Denver International Airport.
Other passengers aboard the flight helped restrain the male passenger, who was removed from the plane at the Denver airport and turned over to authorities.
No other information was immediately available.
FBI officials didn't return messages.
