United Flight 570 from Denver to Salt Lake City turned back just before taking off after a man on board started yelling about a bomb and hitting other passengers on April 15, according to reports.

In a Facebook post and comment, witness Tara Kraatz said: “He opened the emergency door after yelling bomb and starting a fight as we pushed off the gate. … He pointed to his seat and said he had a box under there.”

These videos show the man deplaning on his own, with a ripped shirt. When he exited authorities were waiting, and he was taken away in a wheelchair, according to witnesses and news reports. Credit: Steve and Tara Kraatz via Storyful
