A threat to three middle schools in Pittsylvania County has been deemed not credible. According to Pittsylvania County Schools Superintendent Dr. Mark Jones, the Pittsylvania County Schools Office was made aware Tuesday morning of a potential threat that was posted on Snapchat.

The post referenced Tunstall, Chatham and Gretna Middle Schools. In response to the potential threat the three schools were placed “secured” meaning all outside doors were locked.

At around 1 pm, following an investigation the Pittsylvania County Sheriff’s Office and School Resource Officers informed Pittsylvania County Schools that the threat was not credible. The source of the post is still being investigated.
