A Michigan high school student accidentally detonated a homemade explosive device he brought to school, injuring himself and four of his classmates, police said.
Police officers responded to Newaygo High School in west-central Michigan at 8:52 a.m. after a report of an explosion inside a classroom, state police said in a tweet. A preliminary investigation determined a 16-year-old student had accidentally detonated a homemade explosive device he brought to school.
The device detonated inside a classroom, injuring the 16-year-old and four classmates sitting nearby. School administrators dialed 911, the school was immediately evacuated and students were transferred to the bus garage as emergency services arrived on scene.
All Newaygo County schools went into lockdown in compliance with the county’s emergency operations plan until authorities determined there were no further threats to students.
