The Moon Area School District will be adding an additional police presence at the middle school and high school today. School officials say they and local police were notified via an anonymous tip of a threat to the school at 8:30 last night. An investigation determined the threat was not credible. However, out of an abundance of caution, both middle school and high school will have added police presence today. All classes and activities will continue as scheduled. The school is also offering counselor support for students and staff that may need it.
