Naperville police are investigating a wave of non-credible threats to about a dozen Naperville schools in the past decade. The most recent threat came from an unknown person threatening violence at Naperville Central High School. The police have notified their federal partners at the FBI and are coordinating with them on these ongoing investigations. The threats disrupt learning environments and increase parents' confidence in their schools being safe. The Naperville Police Department will not tolerate such threats and will seek felony charges against those found to be responsible.
