KNOXVILLE, Tenn. (WATE) — The Knox County Sheriff’s Office is investigating separate threats made online to a pair of local high schools, causing a precautionary evacuation at one.

Powell High School was evacuated by school officials as a precaution and detectives interviewed students, a Knox County Sheriff’s Office spokesperson said. At 2 p.m., the spokesperson shared that the school had been cleared.

A threat was also made to Carter High School. The school was placed on a lockdown that has since been lifted.
