(FRANKFORT) - Students at Frankfort High School waited in line at the gym entrance to go through airport style security this morning.
Authorities said a non-specific threat was found inside the school building over the weekend.
K-9 units swept the high school early this morning, but found nothing suspicious.
All students went through metal detectors stationed at the gym entrance as a precaution.
Wednesday is the last day of class before summer vacation at the school.
