Two security officers were fired but three other employees were suspended over misleading statements and leaving out information in reports.
Community members protest the treatment of Dr. David Dao, who was forcibly removed from a United Airlines flight by the Chicago Aviation Police, at O'Hare International Airport in Chicago, Illinois, U.S., April 11, 2017. Also, the Inspector General's report should become the poster child for why passengers should always maintain the right to videotape mistreatment of all kinds. Dao suffered a concussion and a broken nose, and lost two teeth, Demetrio said. It was also revealed that a supervisor was sacked after the deliberate removal of facts from an employee report.
Five-day suspensions were handed to two other aviation security officers who boarded the plane and dragged a bloodied and flailing Dr. David Dao down the aisle for refusing to give up his seat for a United crew member who needed to get to Louisville.
The Aviation Department said a review of its policies and procedures was ongoing and would be completed by the first quarter of 2018, The Chicago Tribune reported. In July, it decided the Chicago Police Department would respond to airport disturbance calls over security officers.
Chicago's inspector general on Tuesday confirmed earlier reports that the officers involved had suggested that it was Dao's fault that he struck his face on an armrest before he was dragged off the plane.More news: Kenyan police kill two protesters amid government ban
According to Ferguson's report, his office's investigation showed that there was "significant confusion" at the Chicago Department of Aviation over the "roles and expectations" of aviation security officers. The ordeal also prompted United's CEO, Oscar Munoz, to publicly apologize.
Despite Dao's plea, the airline insisted and as a result, they sent security onto the plane, where they were told to remove him from the aircraft.
But viral video of the incident fast became an worldwide symbol of passenger discontent with the flying experience and a civic embarrassment that damaged Chicago's reputation as an global tourist destination.
Mr Dao's lawyer Thomas Demetrio said his client was "neither vindictive nor happy", adding: "There is a lesson to be learned here for police officers at all levels".
