In a court filing, the FBI said Abdullah, also known as Christopher Thomas, was an imam, or prayer leader, of a radical group named Unmah whose primary mission is to establish an Islamic state within the United States.
No one was charged with terrorism. But Abdullah was “advocating and encouraging his followers to commit violent acts against the United States,” FBI agent Gary Leone said in an affidavit.
“He regularly preaches anti-government and anti-law enforcement rhetoric,” Leone said. “Abdullah and his followers have trained regularly in the use of firearms, and continue to train in martial arts and sword fighting.”
Leone said members of the national group mostly are black and some converted to Islam while in prisons across the United States.
