An Argentine judge has lifted an arrest warrant for the 87-year-old president of the Mothers of the Plaza de Mayo human rights group in a highly politicized embezzlement case.

The investigating magistrate had ordered Hebe de Bonafini's arrest on Thursday.

But hundreds of supporters massed outside the group's offices to prevent police from removing her. The judge agreed Friday to allow her to be questioned without being jailed. A date was not set.

De Bonafini had twice refused to submit to questioning in a case involving the alleged diversion of nearly $14 million in public funds earmarked for a low-incoming housing project registered under the Mothers' name.
