New York ? A millionaire convicted of helping his wife keep two Indonesian housekeepers as virtual slaves was sentenced Friday to more than three years in prison, ending a trial that shed light on the often little-seen exploitation and abuse of domestic workers.

International perfume maker Mahender Sabhnani, 51, was sentenced to 3 1/3 years and fined $12,500. He was convicted in December on a 12-count federal indictment that included forced labor, conspiracy, involuntary servitude and harboring aliens.

The victims testified that they were beaten with brooms and umbrellas, slashed with knives, and forced to climb stairs and take cold showers for misdeeds that included sleeping late or stealing food from the trash because they were poorly fed.
