Iowa student suspected of making explosives

Authorities have confiscated homemade, chemical-based explosives from the home of a student in the northern Iowa town of Rolfe.

Ron Humphrey of the State Fire Marshal Division says about a quarter pound of the explosive was found Thursday and that the material could have seriously injured someone, had it exploded.

Pocahontas County Sheriff Bob Lampe says an adult and a juvenile have been detained and will be charged.

Classes in the Pocahontas Area Community School District were dismissed early Thursday afternoon as a precaution. Superintendent Joseph Kramer says there were no direct threats against the school, its students or staff members.
