United Airlines is in hot water Monday over a disturbing incident on a plane from Chicago to Louisville, Ky., Sunday, as a man was forcibly dragged out of an overbooked plane for not volunteering to leave.

Video from the incident shows a man being grabbed by men with badges and radios — it's not clear if they're police officers or private security guards — grabbing a middle-aged man from his seat and dragging him into the aisle. The man screams and appears to be injured as he's dragged through the aisle of the plane.

The Louisville Courier-Journal reported United overbooked the flight and needed four people to take a different flight so a flight crew could make it to Louisville for a Monday morning flight. The airline reported it first offered $400 and a hotel room for volunteers, but found no takers.

The airline then upped the offer to $800 and a hotel room, but no one took the offer so a computer randomly selected four passengers. The report indicated three of them left the airplane with no incident.

However, the man said he was a doctor who needed to treat patients at a hospital in Louisville in the morning and had to be on the flight.

Three security guards were called and one of them threw the man into the armrest before putting him on the floor, according to a witness. He was dragged off the plane, but was apparently allowed back on.

The witness told the newspaper he appeared to be bloodied and disoriented when he came back on the plane and ran to the back. Passengers were then taken off the plane so the flight crew could clean up before taking off. The flight was delayed about two hours in total.

"Flight 3411 from Chicago to Louisville was overbooked," a United spokesperson told the paper. "After our team looked for volunteers, one customer refused to leave the aircraft voluntarily and law enforcement was asked to come to the gate."
