COEUR D’ALENE — A lockdown at Lake City High School was accidentally initiated Wednesday morning, causing a response from local law enforcement agencies who rushed to the campus.

The Coeur d’Alene Police Department, the Kootenai County Sheriff’s Office and the Coeur d’Alene School District were all on scene following notification that an incident had occurred.

In a lockdown, all internal and external doors are secured until such time as law enforcement declares the situation safe and secure, the school district wrote in a press release. They’re initiated for “real or perceived threats to student and staff safety.”

The lockdown started “when a key fob used to activate a lockdown unintentionally passed in front of an access control sensor while trying to open a door,” a spokesperson said. School officials notified parents and staff through a mass communication system.

“While this was a preventable event, we are impressed with the response of our partners in law enforcement. They acted quickly and professionally to ensure our students and staff were safe,” said Mike Nelson, deputy superintendent. “We are a learning organization and will use this experience to be better prepared when a lockdown is necessary.”

When asked how the district plans to avoid this mistake again, the spokesperson said, “After each incident, we conduct an after action to evaluate what happened, the response and identify areas for improvement.”
