Michigan man, 19, accused of planning mass shooting at military base on behalf of ISIS

A former Michigan Army National Guard member is accused of attempting to carry out a mass shooting at a U.S. military base in Warren, Michigan, on behalf of the terrorist organization ISIS. 

Ammar Abdulmajid-Mohamed Said, 19, of Melvindale, Michigan, was arrested Wednesday after officials foiled his alleged planned attack at the U.S. Army's Tank-Automotive and Armaments Command facility at the Detroit Arsenal. 

According to a criminal complaint, Said reportedly told two undercover officers of his plans for a mass shooting at the base. Officials say that in April 2025, those two undercover officers agreed to carry out Said's plan under the direction of ISIS.
