An Arizona man accused of helping a New York college student join the Islamic State in Syria will remain in federal custody.

At a detention hearing Tuesday in Phoenix, a federal judge ruled Ahmed Mohammed el Gammal is a flight risk, and he’ll remain in custody pending any further review by the Southern District of New York.

His trial date hasn’t been set yet.

Gammal was indicted last week in Manhattan federal court, where the case is being prosecuted.

He allegedly helped a 24-year-old student travel to Syria and receive military and religious-style training earlier this year.

The 42-year-old Gammal was arrested in the Phoenix suburb of Avondale on a criminal complaint unsealed Aug. 26 in New York.

Gammal’s attorney didn’t answer questions about the case after Tuesday’s hearing.
