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.
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, the FBI said.
Investigators did not specify which church Abu-Rayyan allegedly was eyeing, but said it has a capacity of 6,000 members, according to a criminal complaint unsealed Thursday in U.S. . .
