BERKELEY HEIGHTS, NJ - Gov. Livingston High School and Columbia Middle School went into shelter in place and lock down following a false report of a threat.

Superintendent of schools Judy Rattner confirmed that the threat involved a school district in New Mexico and the Berkeley Heights school district is safe. "The student that initiated the threat is currently in custody and all of our students are safe," said Rattner. 

She reminded the parents, "please, in order to secure and provide safe schools for all of our students, if you see something or hear something of concern, please make sure to report it immediately so that we can continue to maintain the safety of our buildings."

A police officer stationed at Columbia Middle School did not confirm the threat, however, the officer confirmed the students are safe.  

Following an investigation, officials determined the posts were related to Belan High School (BHS) in New Mexico, according to multiple Facebook posts.

According to News-Bulletin.com, a newspaper serving Valencia County, New Mexico since 1910, local police in Los Lunas, New Mexico, where Belan High School is located, identified the student as 16 year old Jonathan Flores, on Thursday night. 

This is the latest of several lockdown incidents in New Jersey since 17 students and faculty were killed at a Parkland, Florida high school last Wednesday. Students at Nutley and Matawan High Schools have also been placed on lockdown but threats against those schools were proven to be unfounded.
