(JTA) — A passerby stopped a schoolboy from stabbing a Jewish classmate in Paris.

The attempted stabbing on Sept. 24 in Paris’ 16th arrondissement ended without serious injury thanks to the intervention of the man who was riding his scooter when he noticed a fight, SPCJ, the security service of France’s Jewish community, reported Thursday.

The attacker hurled anti-Semitic insults at the boy, including “dirty Jew” and threatened to kill him while brandishing a knife. He also punched the Jewish boy, SPCJ reported.

The passerby helped the 16-year-old Jewish boy, identified only as A., fend off his attacker, and took the boy on his scooter to police, who later arrested the suspected attacker. The report did not name any of the people involved.

According to the report, the violence started after the attacker demanded the victim give him his wallet during class at school, while the teacher was away.

The Jewish boy refused and the attacker followed him out of school accompanied by three friends, who helped the attacker corner the Jewish boy.

The attacker’s friends also prevented him from stabbing the Jewish boy by restraining him, but he broke loose of their hold and picked up the knife again until the passerby intervened.
