The Butler Area School District’s high school and intermediate high school operated on a modified lockdown Wednesday, Sept. 11 due to a vague threat posted on a social media site.

Superintendent Brian White said police were at the schools that morning, investigating to determine if any threat exists.

“We received what was referred to me as a vague threat,” White said Wednesday as he was arriving at the campus. At that time, he said he had no other information about the threat.

He alerted parents in a message that was sent at 8:16 a.m.

“We have been made aware of a vague threat to secondary schools circulating in the region. We are not aware of any threats at the elementary level at this time,” White said in the email. “Although we do not have an indication there has been a specific threat to the Intermediate High School or Senior High School, we have taken precautions to ensure the safety of our students.

“Both the IHS and SHS are now operating in a perimeter lockdown. In addition, local police have been notified and will have more of a presence on our school campuses.”

He continued to say that the district takes all threats seriously and asked if anyone sees or hears “any disturbing statements involving our schools or students” to immediately report it to the school district and local law enforcement.

During the modified lock down, gym classes will not be held outside and students will not be allowed outside between classes, White said.
