An unfounded threat forced Manor Middle School to briefly evacuate Wednesday afternoon.
Students and staff were cleared from the building after a "verbal threat of violence" was reported.
Killeen ISD Police immediately responded and notified the Killeen Police Department.
After an investigation by authorities and campus administration, it was determined that the threat was unfounded.
Everyone was released and allowed to return to the building following the all clear.
"Our students must understand that we are serious about school safety and any students making or spreading false, unverified threats, against our schools will be prosecuted to the fullest extent of the law. These false rumors spark fear among students and families, cause severe disruption to the learning environment, and will not be tolerated," said Killeen ISD in a memo to parents.
