A security guard at the children’s Jewish school told investigators that the nanny had complained about the family’s refusal to raise her pay and made antisemitic remarks.

French prosecutors opened a case Tuesday against an Algerian nanny accused of placing toxic household products into food and drink used by the Jewish family that employed her, Le Parisien reported.

The woman, identified as Leïla Y., is being tried in Nanterre for administering harmful substances with a racial motive.
