BRANFORD, Conn. (WTNH) — A 13-year-old attending a Branford High school football game was arrested for breach of peace after showing off a knife, according to officials.

After seeing the knife during the Friday night game, students then let school security know about the weapon, according to police. There was not a fight, and no one was injured.

Branford Public Schools Superintendent Christopher Tranberg sent out a message to parents to alert them of a knife being at the game.

“While privacy rights prohibit the Branford Public Schools from providing any information regarding specific students, safety and security is our priority,” Tranberg wrote in a message to parents. “Any threats or actions jeopardizing members of our learning community are taken seriously and the District, in collaboration with the Branford Police Department, will continue to carry out appropriate measures to keep our schools safe.”
