Newtown High School 'Locked In' Following Threat

NEWTOWN, Conn. (AP) — Visitors have been barred from Newtown High School for the afternoon after school officials discovered a threat on social media.

Schools Superintendent Joseph Erardi sent an email to parents Tuesday notifying them of the lock-in at the high school.

The lock-in allows classes to continue on a normal schedule, but increases security and prevents visitors from entering the building.

The threat follows an evacuation last month at the temporary Sandy Hook Elementary School in Monroe following a threat received there.

A December 2012 shooting at the former Sandy Hook school building left 20 students and six staff members dead.
