Columbine High School and nearby schools in Colorado were placed of lockout status after a series of threatening phone calls.
Under the lockout, school business goes on as usual, but no one can enter or leave the building. The alert has since been lifted.
“We’ve had several phone calls back-to-back threatening Columbine High School,” [sheriff’s spokesman Mark ] Techmeyer said. “We’ve had hundreds of these since the massacre and we take them all seriously. It is normally a short-lived event.”
In 1999, Columbine High School became the scene of one of the nation’s worst massacres when two students killed 12 students and a teacher. Before committing suicide, the two injured 24 other students.
Deputies have been dispatched to the high school.
