A Michigan high school student injured himself and four other students after accidentally detonating a homemade explosive device that he brought to school, police said Monday.
The Newaygo Police Department was dispatched to Newaygo High School on Monday morning after an “explosion inside a classroom,” Michigan State Police confirmed in a statement on Twitter.
The state police said that a 16-year-old student, who was not publicly identified, “accidentally detonated” the device that he brought to school.
The 16-year-old was taken to the hospital with moderate to severe injuries. The four other injured students were taken to an area hospital for minor injuries, and a teacher at the school also sought medical treatment over reported inhalation concerns.
“The investigation continues into what kind of material was involved in the explosion and the circumstances contributing,” the state police said in the Monday statement.
Michigan State Police spokesperson Michelle Robinson said during a Monday press conference that officials do not believe the student with the device had “malicious intent” and that the detonation was an “isolated incident.”
The high school was evacuated following the detonation, and all Newaygo County Schools went into lockdown, according to state police.
Investigators executed a search warrant at a Newaygo home, though they did not provide any additional details on the ongoing investigation.
