GARDEN CITY, N.Y. - A millionaire couple accused of keeping two Indonesian women as slaves in their luxurious Long Island home and abusing them for years have been indicted on federal slavery charges.

Varsha Mahender Sabhnani, 35, and her husband, Mahender Murlidhar Sabhnani, 51, operate a worldwide perfume business out of their home, contracting with overseas factories to manufacture the fragrances.

The two were arrested last week after one of their servants was found wandering outside a doughnut shop on Long Island, wearing only pants and a towel. The woman was believed to have fled the home in Muttontown, a tony community on Long Island's north shore, when she took the trash out the night before.

The couple pleaded not guilty in U.S. District Court, and a magistrate judge set bail at $3.5 million and imposed home detention with electronic monitoring.

An indictment handed up Tuesday night formally charged with them with two counts of forced labor and added two counts of harboring illegal residents.
