Teacher Is Arrested After Threat Closes Schools in Montclair, N.J.

Public schools in Montclair, N.J., were closed on Monday after a teacher at an elementary school threatened its principal on social media, the police said. Several hours later, the school district announced that the potential threat had been “neutralized.”

The teacher, Amir Doctry, was arrested in Philadelphia on Monday morning and charged with making terroristic threats, a spokesman for the Montclair Police Department, Lt. Terence Turner, said.

Mr. Doctry, a teacher at Northeast Elementary School, was put on administrative leave last week when he started showing signs of “erratic behavior,” Lieutenant Turner said. Mr. Doctry was in a “manic state” when he was apprehended and taken to a Philadelphia hospital for a psychological evaluation, Lieutenant Turner added.

The Montclair Police Department said it was increasing patrols around all schools out of an abundance of caution. The department added that there was “no further danger” to Montclair, a township in Essex County, N.J., that is about 20 miles from New York City by car.
