LITTLETON, Colo. (KDVR) —Twenty-three JeffCo Public Schools were placed on lockout Thursday morning after a reported threat at Columbine High School, the Jefferson County Sheriff’s Office said.
The sheriff’s office said that the threat came around 9:20 a.m. claiming that there were explosive devices inside the school. The caller claimed to be hiding outside with a gun.
Nothing has been found to validate the threat, according to the sheriff’s office.
The 23 schools were in the Columbine, Chatfield and Dakota Ridge areas, JeffCo Public Schools said. Lockout means that students can only remain inside and that entry is restricted.
The sheriff’s office said that parents are not allowed to pick up their children until they are released at 2:45 p.m.
Authorities said that all students and staff are safe.
“Unfortunately, we receive many threats like this to Columbine,” Mike Taplin with the sheriff’s office said. “We respond to each threat appropriately, which is what we’re doing now.”
The sheriff’s office is continuing to investigate.
