(AP) – A federal grand jury has indicted a Florida man on a charge of interfering with a flight crew after his unruly behavior aboard a Southwest Airlines flight led to an emergency landing in Texas.

U.S. Attorney Sarah R. Saldana said 29-year-old Ali Reza Shahsavari of Indialantic, Fla., made his initial court appearance Thursday, two days after his arrest at Rick Husband Amarillo International Airport.

An indictment says Shahsavari became disruptive during a flight from Los Angeles to Kansas City, Mo., intimidating flight crew members by screaming profanities and damaging a lavatory.

A detention hearing before U.S. Magistrate Judge Clinton E. Averitte in Amarillo was scheduled for Tuesday. A court official didn’t immediately return a phone call seeking information on an attorney for the suspect.
