Washington- A US Federal Judge in Minneapolis (State of Minnesota) has ordered an American-Somali man to remain in custody for watching a documentary on terrorism while in detention.

Abdullahi Yusuf, 21, was sentenced last year for trying to join ISIS. But he violated the terms of his probation by watching a documentary on terrorism and terrorists at his halfway house.

Minneapolis Star Tribune said Thursday that US District Judge Michael Davis ordered Yusuf remain in custody until a hearing next week, when a federal judge is expected to decide whether he violated the terms of his probation.

Yusuf was one of nine young men sentenced last year after a long FBI investigation into ISIS recruiting in Minnesota’s Somali community.

He was arrested at Minneapolis airport while on his way to Turkey.
