A Hasidic rabbi and three of his sons are suspected of sexually abusing at least four female relatives, police officials tell NY1.
Investigators say the four sisters from a Brooklyn family were abused sexually for 15 years by their father and brothers.
Two of the brothers were arrested -- one of whom was taken into custody in Brooklyn on East Fourth Street.
Police say their father and another brother fled earlier this week to Israel and were apparently driven to the airport by the mother.
The mother and father of the girls are themselves cousins, according to police.
Sources say the investigation began after one of the daughters -- now ages eight to 20 --confided in a co-worker at the Jewish school where she works.
The New York City Police Department is working with Israeli authorities trying to catch the two men still on the loose.
