 A video posted on Facebook late Sunday evening shows a passenger on a United Airlines flight from Chicago to Louisville being forcibly removed from the plane before takeoff at O’Hare International Airport. 
 
 The video, posted by Audra D. Bridges at 7:30 p.m. Sunday, is taken from an aisle seat on a commercial airplane that appears to be preparing to take flight. The 31-second clip shows three men wearing radio equipment and security jackets speaking with a man identified as Elizabethtown doctor David Dao seated on the plane. After a few seconds, one of the men grabs the passenger, who screams, and drags him by his arms toward the front of the plane. The video ends before anything else is shown. 
 
 A United spokesperson confirmed in an email Sunday night that a passenger had been taken off a flight in Chicago. 
 
 "Flight 3411 from Chicago to Louisville was overbooked," the spokesperson said. "After our team looked for volunteers, one customer refused to leave the aircraft voluntarily and law enforcement was asked to come to the gate. 
 
 "We apologize for the overbook situation. Further details on the removed customer should be directed to authorities."

 Bridges, a Louisville resident, gave her account of the flight Sunday night. 
 
 Passengers were told at the gate that the flight was overbooked and United, offering $400 and a hotel stay, was looking for one volunteer to take another flight to Louisville at 3 p.m. Monday. Passengers were allowed to board the flight, Bridges said, and once the flight was filled those on the plane were told that four people needed to give up their seats to stand-by United employees that needed to be in Louisville on Monday for a flight. Passengers were told that the flight would not take off until the United crew had seats, Bridges said, and the offer was increased to $800, but no one volunteered. 
 
 Then, she said, a manager came aboard the plane and said a computer would select four people to be taken off the flight. One couple was selected first and left the airplane, she said, before the man in the video was confronted. 
 
 On Monday, United released a statement from CEO Oscar Munoz: "This is an upsetting event to all of us here at United. I apologize for having to re-accommodate these customers. Our team is moving with a sense of urgency to work with the authorities and conduct our own detailed review of what happened. We are also reaching out to this passenger to talk directly to him and further address and resolve this situation."

 Bridges said the man became "very upset" and said that he was a doctor who needed to see patients at a hospital in the morning. The manager told him that security would be called if he did not leave willingly, Bridges said, and the man said he was calling his lawyer. One security official came and spoke with him, and then another security officer came when he still refused. Then, she said, a third security official came on the plane and threw the passenger against the armrest before dragging him out of the plane. 
 
 The man was able to get back on the plane after initially being taken off – his face was bloody and he seemed disoriented, Bridges said, and he ran to the back of the plane. Passengers asked to get off the plane as a medical crew came on to deal with the passenger, she said, and passengers were then told to go back to the gate so that officials could "tidy up" the plane before taking off. 
 
 Bridges said the man shown in the video was the only person who was forcibly removed. 
 
 "Everyone was shocked and appalled," Bridges said. "There were several children on the flight as well that were very upset." 
 
 The flight was delayed around two hours before it could fly to Louisville, and it arrived in Kentucky later Sunday night. No update was given to the passengers about the condition of the man forcibly removed, Bridges said. 
 
 The Chicago Department of Aviation said Monday afternoon that it had placed the security officer who pulled the man out of his seat on leave pending a “thorough review” of the situation. 
 
 The aviation department said in an emailed statement that the incident wasn’t in accordance with its standard operating procedure and the officer’s actions “are obviously not condoned by the Department.” 
 
 The department confirmed that all three men who were seen on video talking to the man who was removed from the flight were aviation security officers.

 @United overbook #flight3411 and decided to force random passengers off the plane. Here's how they did it: pic.twitter.com/QfefM8X2cW — Jayse D. Anspach (@JayseDavid) April 10, 2017 
 
 According to the passenger who filmed the video, United initially asked if four volunteers on the flight from Chicago to Louisville would be willing to give up their seat for $400, a free night in the hotel, and a flight at 3 p.m. Monday. The plane required the seats for flight crew members, who were needed in Louisville in order to arrive in time for their next flights. When no passenger accepted the trade, the airline doubled the offer to $800. When still no one accepted, United reportedly used a computer to randomly choose passengers who had already boarded the flight to be required to give up their seats. 
 
 After two people willingly left the plane, the man in the video reportedly said he was unwilling to surrender his seat because he was a doctor and had patients to see in the Louisville area Monday morning. He was then aggressively dragged from the plane, his face bloodied by officers forcing him out of his seat. Passengers filmed the incident, and the man can be heard screaming in captured footage. The man was eventually allowed to re-board the plane, which left with a two-hour delay. 
 
 "Everyone was shocked and appalled," said Audra D. Bridges, who recorded the video and gave her account of the events to The Courier-Journal. "There were several children on the flight as well that were very upset."

– People are outraged after video surfaced Sunday night showing a passenger being forcibly and violently removed from a United Airlines flight that had been overbooked. As the Courier-Journal reports, four seats were needed on the Chicago-to-Louisville flight so that crew members could get to Louisville for a flight assignment Monday morning. Passengers were told that volunteers were needed to give up their seats and that they would receive $400, a hotel stay, and a flight the following day. They were told the flight wouldn't take off until four people had given up their seats, but no one volunteered. The airline then doubled the offer to $800 and still no one volunteered. A manager then came on board and used a computer to randomly select passengers who would need to leave the flight. A couple was selected and left, and then the man in the video was selected. He explained that he's a doctor and had patients he needed to see Monday morning, but was told that security would be called if he didn't exit the flight voluntarily. He said he would be calling his lawyer, and eventually, three security officials came onboard, pulled him from his seat, and dragged him down the aisle and off the plane. Passengers say everyone on the flight was appalled, and children onboard were scared. The man got back on the plane, reportedly "disoriented" and with his face bloodied, and ran to the back of the plane. A medical crew came aboard and passengers were asked to return to the gate while the plane was "tidied up." Eventually the plane departed two hours late. United has since apologized for overbooking, the Week reports, but no update has been given on the passenger who was removed. Video of the incident from two different angles is here and here.
