Federal officials decided not to punish United Airlines over an infamous incident in which a passenger was dragged off an overcrowded plane.

The Transportation Department said it found no evidence that United violated David Dao’s civil rights in the April 9 incident in Chicago. There was also not enough evidence that the airline violated rules regarding bumping passengers to take the case further, the department said.

A Transportation Department lawyer told United about the decision in a May 12 letter but didn’t make the matter public. An advocacy group, Flyers Rights, released the letter on Wednesday.
