Doctor Violently Dragged From United 3411... What Happened?

A doctor was violently dragged from United Express 3411 after gate agents could not find seats for United employees who were deadheading a flight to the next city. After no one volunteered the employee ‘randomly’ picked two sets of passengers to get off the plane, one of which had to be forcibly dragged off but then was able to reenter after the altercation.

CORRECTION: The passenger was allowed to come back on but then was pulled back off again.
