The Indian River District Schools have been placed on lockdown.
The East Millsboro Elementary School got a phone call from an unknown person at around 9:50 a.m. who threatened to do harm to the students.
The Salisbury Daily Times reports that all of the students were called back to their schools while police looked into the situation.
The lockdown was a precautionary measure with an automated alert sent out by the school officials, which said that the students were secure and that teaching had resumed.
