CHICAGO, Ill. (WHAS11) -- Disturbing footage sent to us 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.

United Airlines gave us this response:

“Flight 3411 from Chicago to Louisville was overbooked. 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.”

There is no word on the condition of the man removed from the plane.

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