BAYONNE, NJ - A second teen was charged for last week's social media school shooting threats.

According to Bayonne Mayor Jimmy Davis, police arrested a local 13-year-old for false public alarm and making terroristic threats after detectives determined the student was responsible for a SnapChat involving a Bayonne private school.

Davis said police determined the teen made a SnapChat post adding All Saints Catholic Academy to the list of Bayonne schools that were targeted in a Twitter post on March 4.

"It was determined that the SnapChat message was meant to indicate that All Saints Christian Academy would also be included in the attack referenced in the earlier message," Davis said on Facebook, referencing All Saints Catholic Academy on West 13th Street. "It is important to note that it was determined, through the detectives investigation, that there was no validity to the threat made in the SnapChat message."

Police also took possession of evidence related to the SnapChat incident, the Facebook post said. The Bayonne Police Department is still investigating the origin of the original Twitter threats.
