The memorial rally held on Sunday in Paris outside the home of Sarah Halimi became contentious after younger members of the Jewish community, reported by Israel Radio to be from the Jewish Defense League, began arguing with the woman’s neighbors and reportedly threw objects at the homes and tried to break into them.

French riot police were called to the scene to disperse the demonstrators, who left after singing the national anthems of both France and Israel and waving Israeli flags, Israel Radio reported. The news outlet put the number of demonstrators at 2,000.

Halimi was found dead on the street in front of her apartment on Monday in the crime-ridden 11th district of the French capital. Her 27-year-old neighbor, reported by Israel Radio to be Muslim, was later arrested in connection with her death. He has been sent for psychiatric evaluation, according to reports. Relatives of Halimi said that she had previously experienced anti-Semitic harassment by a relative of the man under arrest. The woman was beaten before she fell from the third floor, Israel Radio also reported.

French police have not classified the woman’s death as a hate crime. French Jewish lawmaker Meir Habib asserted to Israel Radio Sunday that the woman was murdered because she was Jewish and not because her alleged killer is mentally ill.
