Anjem Choudary, the U.K.'s most infamous radical preacher, has been sentenced to 5 1/2 years behind bars for supporting ISIS.
U.K. counterterrorism officials have been after Choudary for almost two decades. He's been linked to hundreds of radicalized U.K. jihadists, including the men who fatally stabbed a soldier on the street in 2013.
But despite his inflammatory rhetoric, the cleric always managed to stay on the right side of anti-terrorism and incitement laws — until he was caught supporting ISIS. The terrorist group is one of the organization proscribed by the Terrorism Act; anyone who invites support for a proscribed group can be imprisoned for up to 10 years.
Choudary will spend his sentence in the high-security wing of a London prison. He's expected to spend a good portion of his term in solitary confinement, since law enforcement is worried Choudary might try to radicalize his fellow inmates.
