Police busted a professional dominatrix accused of running a high-priced sex den out of her Bedford Hills mansion.

According to police, they received an anonymous letter in December saying there was an unusual amount of traffic coming in and out of the Haines Road home. Police say the letter also referred to a Web site called the Sovereign Estate, which indicated dominatrix-type services. Police say the site also featured sex paraphernalia and pictures of 46-year-old Sandra Chemero engaging in sex acts with customers.

After a two-month investigation, an undercover officer was sent in to the home and met with Chemero. Investigators say she agreed to engage in sexual contact with the officer at a later date. Police came back with a search warrant and seized numerous items. Chemero was arrested and is charged with prostitution.
