BROOKLYN - Police say they're investigating a sexual-abuse case where four Brooklyn sisters were abused by their father and three of their brothers. Investigators say that the sisters, who are between the ages of 8 and 20, were abused at a home in Kensington over the course of 15 years.

Police have arrested two of the brothers, one of whom is a minor. The father and the third suspected brother have fled to Israel, investigators say, and are currently being sought.
