A high school in western Michigan reopened Tuesday, a day after a student accidentally detonated a homemade explosive in a classroom.
Newaygo High School was found to be safe after vents and the heating and cooling system were checked, the district said.
“Law enforcement and school administrators met with students to review the situation and share any pertinent details about what had happened,” the district said in a statement.
Police said a 16-year-old boy brought a homemade explosive to school Monday and accidentally detonated it, injuring himself, four other students and a teacher. The boy’s injuries were described as “moderate to severe.”
Newaygo Police Chief Georgia Andres said the student showed a “severe lapse in judgment” but it “was definitely not something he intended.”
WXMI-TV reported that more explosives were found at a residence and safely detonated by authorities.
