McBride Elementary in St. Helens was placed under lock-in Friday morning, June 3, after a threat was made against an employee of the school.
When initially contacted for comment, McBride Elementary would not confirm that the school was placed under lock-in and deferred comment to district administrators.
St. Helens police officers were called to the school, but the nature of the threat has not been released.
The lock-in was lifted at 10:35 a.m., according to Amanda Stuber, the assistant to the superintendent. A lock in typically means students may not leave their classrooms.
Superintendent Patricia Adams said schools perform lock-ins anytime there's a threat near any of the district's campuses.
Parents were notified via phone messages, text messages or emails, she said.
