PARIS (AP) — An escapee from a psychiatric institution slashed a rabbi and his son with a box-cutter on Tuesday, prompting witnesses to tackle and subdue the attacker after a chase through a Paris synagogue, officials said.

The rabbi, who is in his late 40s, was recovering from surgery for a neck injury and his 18-year-old son sustained lesser injuries in the attack north of a touristic shopping area near Paris’ gilded Opera Garnier, according to police and judicial officials and Richard Prasquier, who heads CRIF, France’s largest umbrella organization of Jewish groups.
