Increased security was present this morning at a school in Jersey City after a teen brought a loaded gun on campus.

The incident happened Wednesday afternoon at James F. Murray School on Stegman Parkway.

Students were screened by a metal detector as they walked to class.

The added security measure comes after a 14-year-old boy was arrested for having a gun on school grounds.

Police are still trying to figure out why the student had a loaded gun in his backpack. 

According to school officials, a parent of another child, who knew about the gun, called the school, and within minutes police identified and arrested the teenager.

School Board President Sudhan Thomas is asking people not demonize the young man, saying, “we are dealing with an eighth-grader.”

The student is being charged with weapons possession.
