Jefferson County School Board said on Twitter: “All schools in Columbine, Chatfield, & Dakota Ridge areas have been placed in lockout due to a suspicious person in the Columbine area. Will update when we have more. Lockout means students remain inside; entry/exit are restricted.”
Jefferson County Sheriff’s Twitter account has warned residents to steer clear of the area.
They said: “JCSO PIOs en route to Columbine High School for reported threats. Please avoid the area.
“Attention parents: DO NOT come to Columbine HS right now to pick up students. They will not be released until 2:45pm.
“They are on lock out at the school (meaning no one can come or go) The kids & staff are SAFE.”
Photos taken at the scene show armed police officers near Clement Park, where a memorial to the Columbine High School massacre is located.
In 1999, two students shot dead 13 people at Columbine High School in what was the deadliest school shooting in US history.
