SMYRNA, Del. — Authorities have arrested two Smyrna high school students in connection with threats involving clowns and bombs.

Local news organizations report that officials arrested a 15-year-old boy and a 14-year-old girl Wednesday on charges of felony terroristic threatening and conspiracy.

Smyrna police spokesman Brian Donner says officials had linked the two to an Instagram post on Monday which stated that clowns would commit violence against Smyrna High School students.

An email was also sent notifying authorities that there were bombs inside the school and inside vehicles in the parking lot.

The school was evacuated after the bomb threat was made. Police later sent an explosive detection K-9 team, which swept and cleared the building.
