CHICAGO — The passenger dragged from a United flight lost two front teeth and suffered a broken nose and a concussion, his lawyer said Thursday, accusing the airline industry of having “bullied” its customers for far too long.

“Are we going to continue to be treated like cattle?” attorney Thomas Demetrio asked.

The passenger, Dr. David Dao, has been released from a hospital but will need reconstructive surgery, Demetrio said at a news conference, appearing alongside one of Dao’s children. Dao was not there.

The 69-year-old physician from Elizabethtown, Kentucky, was removed by police from the United Express flight Sunday at Chicago’s O’Hare Airport after refusing to give up his seat on the full plane to make room for four airline employees.

Cellphone video of him being pulled down the aisle on his back and footage of his bloody face have created a public-relations nightmare for United.
