NEWTON >> Three incidents of anti-Semitic graffiti have been reported at Newton North High School since a basketball game at which student fans of the opposing team chanted "You killed Jesus."

Catholic Memorial student fans made their chants last Friday knowing Newton North has many Jewish students. Newton North students had taunted students of the all-boys school with chants that some thought were homophobic.

Newton North's interim principal notified parents of the latest incidents in a letter Wednesday.

Superintendent David Fleishman tells The Boston Globe that police are investigating whether there is a connection between the basketball game and the swastikas found this week, but he said there is no evidence to suggest Catholic Memorial students were involved.

Catholic Memorial officials apologized and the students were reprimanded.
