Knoxville Police say several schools in the Cedar Bluff area put on lockdown this morning after a threat is posted on social media.

KPD says School Resource and Security Officers are following up and conducting safety sweeps where calls are received out of an abundance of caution. At this time, there are no known credible threats to any schools in Knoxville.

Parents of Knoxville Catholic students were alerted to a soft lockdown this morning due to a situation in the Cedar Bluff area.

A soft lockdown means students are in classrooms and teaching is still going on but students cannot leave rooms without a teacher or administrator.
