A new video has emerged showing Dr David Dao arguing with security officers just before he was dragged out of his seat in a United Airlines plane at Chicago's O'Hare International Airport.
Footage shot by passengers showing a screaming Dr Dao being dragged along the aisle of the plane on Sunday has been shared worldwide and has led to a backlash against the American carrier with calls to boycott the airline and charges of racism.
United has apologised for the forcible ejection of Dr Dao and said it is reviewing its policy on bumping passengers off flights.
The new video, which the The Daily Mail says was taken by a passenger sitting behind Dr Dao, shows him talking on the phone as a police officer and a flight attendant stand in the aisle.
He is overheard telling them: "I'm a physician, have to work tomorrow, 8 o'clock."
He speaks on a mobile phone and tells the person on the line that "they want to remove me right now" . He also talks about "a lawsuit against United Airlines".
"No, I'm not going," he says, shaking his head. "I'm not going, you can drag me... I'm not going... I'm staying right here."
When the officer says: "I'm just telling you, it's going to be a lot harder for you...", Dr Dao replies: "Yes I know that, I'd rather go to jail.'
He says that that he had flown from Los Angeles, and have had a long flight.
"I spent almost 24 hours," he says. The flight was bound for Louisville, Kentucky.
The video is cut off then.
The incident started when the airline offered vouchers to passengers to take a later flight to make room for crew members who had to be in Louisville for a Monday flight. When nobody took up the offer, the crew randomly selected four passengers.
Three agreed to go and the fourth, Dr Dao, rejected the offer to take a later flight.
After the first video went viral on social media, United attracted more controversy when a leaked staff memo showed that the CEO, Mr Oscar Munoz,called Dr Dao "disruptive and belligerent".
Mr Munoz has since apologised for his remarks and said the airline will stop using law enforcement officers to remove overbooked passengers from planes.
As of Tuesday, Dr Dao, a Vietnamese-American, was still in a Chicago hospital. His lawyers have filed an emergency request with an Illinois state court to require the carrier to preserve video recordings and other evidence related to the incident.
Shares of United Continental fell as much as 4.4 per cent on Tuesday, but later recovered. Nearly US$1 billion ($1.39 billion) of the company's value was erased in trading on Tuesday (April 11).
