FBI: Dearborn Heights man plotted ISIS style attack at Detroit church

The FBI says a Dearborn Heights man plotted to attack a Detroit church.

The suspect never said which church he planned to attack, but according to investigators they identified a possible target less than half mile away from where the man worked.

The sworn affidavit describes the chilling details what could have been a deadly terror attack in Detroit. The 21-year-old Khalil Abu-Rayyan allegedly told an undercover agent on social media he "Tried to shoot up a church one day. I don't know the name of it but it's close to my job. One of the biggest ones in Detroit. I had it planned out. I brought a bunch of bullets. I practiced a lot with it. I practiced reloading and unloading, but my dad searched my car one day and he found everything. He found the gun and the bullets and the mask I was going to wear."

When asked why he targeted a church, Abu-Rayyan allegedly responded, "it's easy, and a lot of people go there, plus people are not allowed to carry guns in church. Plus it would make the news. Everybody would have heard. Honestly, I regret not doing it. If I can't go do jihad at the Middle East I would do a jihad over here."

Now Abu-Rayyan will be in court Monday for a detention hearing, then on Feb.16, for a gun and drug possession charge, stemming from an arrest in October and Detroit.

With that being said, and based upon everything in this affidavit, it seems very much possible the U.S. Attorney's office will file additional charges against him.

It is unclear how Abu-Rayyan was radicalized but from the affidavit we know that he was an ISIS supporter.

The  affidavit paints a chilling picture of a young man so radicalized he kept the sword in his car and dreamed of beheading people.

Abu-Rayyan's neighbors were shocked to hear of the allegations.

“To say you want to kill all the people, there’s something wrong with your brain,” said one neighbor.

FOX 2 stopped by his house but no one was there.

The affidavit says Abu-Rayyan had demonstrated support for ISIS on social media, retweeting, liking and commenting on the terror group's propaganda videos of a Jordanian fighter being burned alive, men being thrown from high rise buildings, and the beheadings of Christians in Egypt.

In fact authorities say he is displaying a known ISIS sign in a social media picture in front of his home for his now suspended Twitter account. in January, someone warned him his account was reported to the Twitter Safety Center.

The FBI's case was built primarily on the work of an undercover agent. right knew Abu-Rayyan is facing a gun and drug possession charge but could face additional charges for the alleged plot involving a church.
