Erie Middle School went on a lockdown at about 11:30 a.m., according to Erie Police Department spokesperson Amber Luttrell. Centaurus High School in Lafayette and Broomfield High were cleared and taken off their hold as of about 11:55 a.m., according to Boulder Valley School District spokesperson Randy Barber.

The high schools had gone into a hold by 11:20 a.m. Each of those two schools had received an unverified threat in a phone call, Barber said.

Boulder Valley School District officials had no reason to believe an even higher security was necessary, Barber said.

Erie Middle School is in the St. Vrain Valley School District.

A hold status means schools keep students and faculty out of the halls and in their classrooms while school operates as normal, according to Barber. Exterior doors remain locked and people cannot go in or out of the buildings, he said.
