A Southeast Polk High School student was arrested Thursday after allegedly setting off a smoke bomb at the school.
The school resource officer says 18-year-old Jason Boothroyd set off the device in a second floor bathroom at 12:03 p.m. No one was injured in the explosion but there was minor damage done. The sprinkler system did turn on.
Students followed the normal routine for a fire drill evacuation of the school and were able to return to classes about a half-an-hour later.
Boothroyd is charged with reckless use of an incendiary device.
