An unruly man who was duct-taped by fellow passengers on a flight from Milwaukee to Dallas has been charged for assaulting a flight attendant.

According to a release from U.S. Attorney for the Northern District of Texas Leigha Simonton, Abdul-al-Jabbar Oloruntoba Olaiya, 29, was charged via criminal complaint with interfering with a flight crew by assault or intimidation within the special aircraft jurisdiction of the United States.

Olaiya injured a flight attendant in an attempt to exit the plane mid-air.

According to court documents, on November 19, roughly two hours into the flight from Milwaukee to Dallas, Olaiya became frustrated with the flight attendant as she worked the forward galley.

Witnesses told law enforcement they heard Olaiya say he was “captain of this flight” and needed to “get off the plane.”

He then allegedly charged the flight attendant in an attempt to access the aircraft exit door. The flight attendant, identified in court documents as S.J., used her body to shield the door and was injured in the scuffle.

Other passengers rushed to assist, tackling Olaiya and duct-taping his wrists and ankles, then keeping him subdued for the rest of the flight. With only 30 minutes left, the pilots continued to DFW, calling the tower for priority landing and taxing. The incident made national news.

Once they landed, Olaiya was removed from the plane by officers and taken in for a mental evaluation. If convicted, he faces up to 20 years in federal prison.

The Federal Bureau of Investigation’s Dallas Field Office and the Dallas Fort Worth International Airport Department of Public Safety conducted the investigation. Assistant U.S. Attorney Levi Thomas is prosecuting the case.
