The trial of Mahender Muralidhar Sabhnani and his wife Varsha Mahender Sabhnani charged with enslaving and abusing two Indonesian women servants opened in a Federal Court in Long Island on Monday.

Mahender Sabhnani, 51, and Varsha Sabhnani, 45, residents of the wealthy enclave of Muttontown in Long Island have pleaded not guilty to a 12-count federal indictment accusing them of conspiracy, involuntary servitude and other charges.

The Sabhnanis, owners of an international perfume business, are free on $4.5 million bail but under house arrest.
