ADRIAN — The Adrian School District has enacted its "shelter-in" policy as a response to a school shooting threat made at Worthington Public Schools Wednesday night on social media.

In a message received by Adrian School District parents, the district said it had no reason to believe there was any threat to Adrian Public Schools, but would respond in the interest of student safety, which is its No. 1 priority.

"When things like this happen so close to us we realize that everyone has a heightened level of concern and are sensitive to the situation," Adrian Superintendent Roger Graff said. "Even though this was not directed at Adrian we wanted to take steps to let our students, staff and families know that we are aware of the situations and assure them safety and security are a top priority."

The shelter-in policy prohibits students from moving in and out of buildings throughout the day unless released with a parent.

The Adrian Police Department will have a strong presence near the schools throughout the day, the message added.

Questions may be directed to Adrian Middle/High School Principal Kate Koehne or Elementary Dean of Students Randy Schettler.
