Asian Man claiming to be doctor bloodied, dragged off overbooked United Airlines flight

Video of cops forcibly dragging a United Airlines passenger from his seat on an overbooked flight went viral on Monday, sparking turbulence before the plane got off the ground.

Some of the shocked passengers gasped in disbelief at O’Hare Airport in Chicago. Others recorded the Sunday evening clash on their cell phones, as the passenger who refused to give up his seat was left bloodied.

“Please, my God!” a passenger hollered.

“What are you doing?” asked another.

The confrontation raised questions about the aggressive tactics and whether the airline or police had the right to boot a paying customer from the flight.

The 5:40 p.m. flight to Louisville, Ky. was delayed two hours, according to airline officials. After passengers finally boarded the flight, United asked for volunteers to give up their seats to four United employees who needed to be in Louisville on Monday for a flight.

When no one budged, it was announced that passengers would be randomly selected for removal.

The man is named David Dao, a source with direct knowledge of the passenger's identity told the Louisville Courier-Journal.
