Parents in Bangor, Michigan received automated alerts on Friday that at least three explosive devices had gone off at Bangor Middle School.

Bangor Public Schools Superintendent Ron Parker confirmed that at least two homemade devices had exploded in a locker at the middle school. Parker said that the simple devices were known as "works" and consisted of drain cleaner and aluminum in soda bottles.

“It wasn’t a big explosion,” Parker recalled. “The locker didn’t even open.”

According to Parker, a 15-year-old special needs student had admitted to placing the bombs after being dared by another student. Security footage reportedly showed the student placing one device in a school bathroom. It was later discovered that the device had exploded in the bathroom as well.

"There’s no doubt who did it and he readily admitted it," Parker explained. The student was being taken into custody by law enforcement on Friday.

There were no reports of injuries, and the third bomb was not confirmed by school officials.
