LIMESTONE COUNTY, Ala. - Ardmore High School was on lockdown for a brief time Tuesday morning due to a threat made on social media.

Superintendent Tom Sisk says a tenth grader is in custody.  He said Ardmore Police brought the threat to the school system's attention.

"We immediately took steps to identify and isolate the student.  We placed Ardmore High School on lockdown and followed our safety protocol," said Dr. Sisk.

Dr. Sisk said the threat was made last night on Facebook, and included a statement that the school's hall would be sprayed with bullets.

"Making a threat on social media is not a joke. It's not a game. We're going to treat it seriously as if you're going to act on it," said Dr. Sisk.  "We will act decisively and deliberately to deter and address those concerns. In Limestone County our board has made it clear the safety of students is at the forefront of what we do every day."

Sisk said school staff determined the student had left campus and was headed to the Limestone Career Technical Center.  Law enforcement arrested him there.

The lockdown was lifted around 9 a.m.  Senior administrators and police are interviewing the student in custody.

"Our response will be deliberate and decisive as we take all threats seriously," said Sisk.
