A dominatrix was arrested on prostitution charges at a suburban estate that she leased from the rabbinical school next door, and school officials faced the unusual prospect of having to cleanse the building once the whips and chains are gone.

"Once everything is out, there has to be a spiritual cleansing," said Rabbi Samuel of the Orthodox Khal Adas Kashau yeshiva. "We won't go close to that place until they move out. No, no, no — heaven forbid."

Sandra Chemero, 46, was charged Wednesday with prostitution and criminal possession of a stun gun at what she called "The Sovereign Estate" — four acres in tony Bedford that she leased last year.

"It's like a calamity," the rabbi said. "I've never heard such a thing, and I don't want to hear about it. It's terrible."

The rabbi, who identified himself only as Rabbi Samuel, said yeshiva officials immediately ordered Chemero's eviction on grounds that she broke the lease by engaging in illegal activity and using the home for a business.

Chemero could not immediately be reached for comment. She has a residential phone in Connecticut, but the number is unlisted.

She advertised her services on a Web site, promising that the estate was "a place like no other. ... There is something unique about serving your mistress in a home designed and appointed especially for her enjoyment."

Photos showed the dominatrix in spiked heels and a low-cut, one-piece black outfit, with a chain around her waist.

Bedford police Lt. Robert Mazurak called the arrest "very unusual for someone in this town," which is home to Martha Stewart, Ralph Lauren and Glenn Close. "It's a quality-of-life issue. We acted rather quickly," he said.

Although there's nothing illegal about working as a dominatrix, Chemero was arrested after a police investigation that began in December turned up evidence of prostitution.
