A 14 year old from Millsboro has been arrested after making a bomb threat at a local middle school Friday evening. Delaware State Police say the incident occurred while the 8th grade formal dance was taking place and the Sussex Emergency Operations Center received multiple calls that there was a bomb in the school. The school was evacuated and a K-9 search showed no explosive device was present. The investigation led police to an Oak Orchard home and the 14 year old boy who made the calls to 9-1-1. He’s charged with terroristic threatening and was released to his parents.
