NEWTOWN, Conn. (AP/PIX11) — A threat on social media has prompted authorities to bar visitors from a Newtown, Connecticut, high school near where an elementary school shooting massacre occurred two years ago.

Schools Superintendent Joseph Erardi sent an email to parents regarding Tuesday’s lock-in at Newtown High School.

“The building was put into a lock-in closed environment because of a threat that was made on social media directly and only to Newtown High school,” a letter posted to the school website said.

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

The school was in lock-in mode for about 40 minutes.

Newtown High School is a little over a mile away from the former Sandy Hook Elementary school, where a 2012 shooting left 20 students and six staff members dead.

Last month the temporary Sandy Hook Elementary School in Monroe was evacuated after receiving a bomb threat.
