A 13-year-old has been arrested and charged with making and online threat Tuesday morning against schools in Bayonne, according to Mayor Jimmy Davis.

Police say that the teen is facing false public alarm and terroristic threat charges for allegedly posting on Twitter, “You think you guys evacuated the school but that was all part of the plan. @BayonneBOE watch your back I’ll be coming.”

Authorities say that the threat was posted as a copycat incident related to separate threats made on Twitter and Snapchat over the weekend against the schools. Those threats prompted the closures of all Bayonne schools Monday.

There was a large police presence at Bayonne schools Tuesday in the wake of the online threats.

Bayonne police say that they are continuing the investigation into who made the other threats against the schools.

Dozens of schools in New Jersey have had to be evacuated or put into lockdown nearly every day due to threats made online or found written since the Feb. 14 mass shooting of a high school in Florida.
