Federal authorities have arrested a Michigan man they say is an ISIS supporter who wanted to carry out an attack on a 6,000-member Detroit church, NBC News reported.
Khalil Abu-Rayyan, 21, of Dearborn Heights, allegedly had guns and a large knife and told an undercover FBI agent that he "tried to shoot up a church one day."
"I bought a bunch of bullets. I practiced reloading and unloading," he said in an online conversation, according to a criminal complaint unsealed Thursday in U.S. District Court.

Investigators did not specify which church Abu-Rayyan allegedly was eyeing but the FBI had been monitoring him for months because of his "increasingly violent threats" about committing acts of terror and martyrdom against churchgoers and police officers on behalf of ISIS.
