A 14-year-old Iowa Falls middle school student is locked up after allegedly phoning in a threat to the school Monday. The school was evacuated after a teacher received a call that there was a bomb in the school. Iowa Falls Police Chief Ron Kuhfus says around 200 seventh and eighth graders were taken to an elementary school. No bomb was found. Kuhfus says the male student made the call from a phone in the school. The boy is being held at the Iowa Juvenile Detention Center in Eldora.
