Delaware State Police have arrested a 14-year-old Millsboro boy on charges of making a bomb threat about Millsboro Middle School while a dance was being held.

Police said the incident happened Friday, May 18 at about 6:02 p.m., during the eighth grade formal dance at Millsboro Middle School on State Street.

The Sussex County Emergency Operations Center began to receive multiple 911 calls from an unknown male caller who stated that there was a bomb in the school.

The state trooper assigned as the school resource officer was already at the school because the dance was taking place. With help from the Millsboro and Dagsboro police departments, the school was evacuated without incident.

In a K-9 search of the school, no explosive device was found.

An investigation determined the phone call was originating from an address in the Oak Orchard area of Millsboro. Troopers went to the residence and found a 14-year-old boy who was confirmed to have made the 911 calls, police said.

The teen was taken into custody and transported to Delaware State Police Troop 4 where he was charged with one count of terroristic threatening. He was arraigned in Justice of the Peace Court 3 and released to his parents on $1,000 unsecured bail, pending an appearance in Family Court.
