A group of Brighton High School students are under investigation for allegedly making a list of people they “might want to harm,” officials said. Brian Ballou, a Boston public schools spokesman, said a “small group of students,” possibly only two, made the list Friday. Ballou did not give any specifics as to who was on the list. The students and their parents were spoken to by school officials, Ballou said. It is not yet clear if they will receive any punishment or charges. “We have no reason to believe there was the intention of actually harming anyone,” said Ballou, who did not name the students involved.
