CHICAGO -- Disturbing footage sent to WHAS-TV from viewers on social media shows a man forcibly removed from a United Airlines Flight headed from Chicago to Louisville on April 9.

The man was forced out of his seat by officials and dragged him down the aisle.

The following are tweets from two people on Twitter of the incident: 

The flight was overbooked, according to United Airlines, so the airline asked for volunteers to leave the aircraft.

This man said he had to get home and refused to voluntarily give up his seat and that's when we are told the police were called to remove him.

"I have to go home, I have to go home, I have to go home," cries a man as he runs the length of a United Airlines passenger plane.

United Airways media representatives declined our requests for a phone interview and would not respond to e-mailed questions.

In a prepared statement, United Airways sent an e-mail KHOU-11 News, which included the following response 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 with him to address and resolve this situation.

There is no word on the condition of the man removed from the plane. Less-widely circulated video has surfaced showing that same man a short while later blood streaming down his face.  The man repeatedly says, "Just kill me. Just kill me."

One passenger said after the incident: " were crying and people are disturbed."
