A guy from Michigan was taken into custody on suspicion of planning an ISIS-sponsored mass shooting targeting a U.S. military installation. Ammar Abdulmajid-Mohamed Said, a 19-year-old former Michigan national guardsman, was arrested by the Justice Department on Wednesday for the unsuccessful attack on a military installation in Warren, Michigan.

The suspect is accused of disseminating information about a harmful device and trying to promote a foreign terrorist group. Wednesday is the date of his first court appearance. He may spend up to 20 years in jail on each count if found guilty. Because of the suspect’s potential to escape and his threat to the community, federal prosecutors are attempting to keep him in jail.

“This defendant faces charges for orchestrating a lethal assault on a U.S. military installation domestically for ISIS,” stated Sue Bai, the head of the Justice Department’s National Security Division. “Thanks to the unwavering dedication of law enforcement, we prevented the attack before any lives were lost. We will not hesitate to deploy the full power of the Department to locate and prosecute those who aim to harm our military personnel and to safeguard everyone Americans.”

At the Detroit Arsenal in Warren, Said intended to carry out the mass shooting at the Tank-Automotive & Armaments Command complex of the U.S. Army. According to a criminal complaint, he disclosed the plot in advance to two undercover law enforcement agents.

He supplied magazines and ammunition for the attack, drone reconnaissance, and firearms training for the undercover cops after the two officers said they wanted to execute Said’s plan on behalf of ISIS, according to the lawsuit. Along with teaching them how to make Molotov cocktails, Said also planned out the attack’s precise logistical elements, including which building to target.

“ISIS is a violent terrorist group that targets Americans for murder.” In addition to being a heinous felony, aiding ISIS or any other terrorist group in planning or executing violent crimes poses a threat to our whole country and way of life, stated Jerome F. Gorgon Jr., the U.S. attorney for Eastern Michigan.

“Anyone who commits acts of terrorism will face the full force of the law, and our office will not tolerate such crimes or threats.”

The suspect proceeded to a location close to the military base in order to launch his drone and start the operation with the intention of carrying out the assault on May 13. When he was apprehended by police, his scheme was thwarted.
