A Bolingbrook teenager, accused of trying to join the terror group ISIS, has been ordered held until trial.
Federal prosecutors say Mohammed Khan posed a flight risk and was a danger to the community.
Khan tried to bring his two younger siblings with him to Syria.
The three were stopped at O’Hare last month before they could board a flight to Turkey.
All three had written letters to their parents saying good-bye.
Khan's 17-year-old sister and 16-year-old brother have not been charged.
The two minors were returned to their parents.
Khan, who is 19-years-old, is charged with attempting to aid a terrorist organization.
