The unruly passenger on a Southwest Airlines flight forced to divert to Amarillo's Rick Husband International Airport on Tuesday has been indicted by a federal grand jury.

29 year-old Ali Reza Shahsavari of Indialantic, Florida was indicted on a charge of interference with a flight crew.

Shahsavari is accused of assaulting and intimidating the flight crew on a flight from Los Angeles to Orlando by being disruptive, screaming profanities and damaging the lavatory- while the flight was in progress.  Passengers also reported that Shahsavari screamed “You’re all going to die. You’re all going to hell. Allahu Akbar”.

Currently, Shahsavari remains in custody pending the results of a detention hearing scheduled for October 25.

If Ali Reza Shahsavari is convicted of the charge against him, he faces a maximum sentence of 20 years in prison and a $250,000 fine.
