A US Attorney's Office statement says Asher Abid Khan was arrested yesterday and charged with conspiracy to provide material support to a foreign terrorist organisation.
A criminal complaint says the 20-year-old Spring resident and a friend planned to travel to Turkey, then Syria, with the intent of joining and fighting with Islamic State.
The documents allege Khan's friend made it to Syria with Khan's help. They say Khan, who had been living in Australia, made it to Istanbul but then his family deceived him into returning to Texas.
