A tense Monday morning unfolded across several schools in the Boulder Valley and St. Vrain Valley school districts after a series of unverified threats triggered lockdowns and holds at Erie Middle School, Centaurus High School in Lafayette, and Broomfield High School.
Erie Middle School became the center of the most significant response after receiving a bomb threat around 11:30 a.m.
The school went into full lockdown as Erie Police Department officers rushed to the scene.
Authorities called in bomb detection K9 units, deployed drones, and conducted a coordinated sweep of the entire campus alongside regional partners from the Louisville and Lafayette Police Departments.
By 1:12 p.m., the lockdown at Erie Middle was cleared to a hold status as officers finished their sweep of the building’s interior.
Then, at 1:50 p.m., Erie Police confirmed the all clear, stating that no evidence of explosives or any legitimate threat to student or staff safety had been found anywhere on campus.
“We understand incidents like this are deeply concerning for students, parents, staff, and the entire community,” the Erie Police Department wrote in a Facebook update. “We appreciate everyone’s patience and cooperation during today’s response as we worked to ensure the safety of all involved.”
School officials indicated the threat may have been a case of swatting, a term used when someone makes a false emergency report to provoke a large law enforcement response.
Meanwhile, Centaurus High School in Lafayette and Broomfield High School both went into a hold status by 11:20 a.m. after each received an unverified threat through a phone call.
Boulder Valley School District spokesperson Randy Barber confirmed both schools were cleared by approximately 11:55 a.m. He declined to describe the specific nature of the threats made in those calls.
The Lafayette Police Department responded to Centaurus at 10:59 a.m. and formally declared the threat not credible around noon.
“The threat is not believed to be credible, but officers are on scene conducting a precautionary investigation,” Lafayette Police posted on X.
Barber clarified what a hold status means for students and families. Under that protocol, students and faculty remain in their classrooms while school continues to operate as normally as possible.
Exterior doors stay locked, and no one is permitted to enter or exit the buildings until authorities lift the restriction.
Boulder Valley School District officials said at no point did they have reason to believe a higher security status was warranted at either high school.
The Erie Police Department noted in an update that several schools across the northern Front Range area received similar threats on the same day, prompting coordinated communication among regional law enforcement agencies and school districts.
The timing of the threats, arriving during the final stretch of the school year, led some community members to speculate on social media that students looking to escape end-of-year exams may have been involved, though no arrests or confirmations have been publicly reported.
Erie Police credited the St. Vrain Valley School District for its professionalism and coordination throughout the response. No injuries were reported at any of the affected schools.
The investigation remains ongoing, and authorities have not yet announced any suspects or additional details about the origin of the calls.
