A retired New York City financier once known as the “right-hand man” of billionaire George Soros has been indicted on charges of abusing women.

According to the New York Post, Howard Rubin, 70, allegedly used his Manhattan penthouse as a “secret sex dungeon” at the center of the case.

In a statement released Thursday, the Justice Department said Rubin and his assistant, Jennifer Powers, have been charged with trafficking and transporting women across state lines for sexual encounters with Rubin.A bank fraud charge was lodged against Rubin “in connection with misrepresentations made to a bank in the course of financing Powers’s mortgage for the Texas home of Powers and her husband,” according to the release.

“It is in this secret sex dungeon that Rubin, now 66, is accused of having committed violent acts and sexual assault against a number of women, including actual Playboy playmates. A civil trial, with six of his seven alleged victims seeking at least $18 million, is scheduled for November,” The Post reported.

Among other alleged acts of deprivation, The Post reported that Rubin has been accused of “beat[ing a woman’s] breasts so badly that her right implant flipped” — an injury so severe that, according to court documents, her “plastic surgeon was not even willing to operate on her breasts.”

Prosecutors allege Rubin paid women up to $5,000 for BDSM encounters. However, several women contend they never consented to the level of violence and humiliation they say he carried out during those sessions.

Another plaintiff claims that, while Rubin allegedly had her bound in his ‘dungeon,’ he told her “I’m going to rape you like I rape my daughter” and then, according to the complaint, forced sex on her against her will.

“Rubin has three children with his estranged wife, including at least one daughter,” The Post added.

“I thought he was a nice guy. He was a nebbishy Jewish guy and totally normal. I was surprised to hear about him having that apartment [with a sex dungeon],” a trader who worked with Rubin at Soros Fund Management, created by billionaire investor George Soros, told The Post.

“As alleged, the defendants used Rubin’s wealth to mislead and recruit women to engage in commercial sex acts, where Rubin then tortured women beyond their consent, causing lasting physical and/or psychological pain, and in some cases physical injuries,” Joseph Nocella Jr., United States Attorney for the Eastern District of New York said in the DOJ release.

“Today’s arrests show that no one who engages in sex trafficking, in this case in luxury hotels and a penthouse apartment that featured a so-called sex ‘dungeon,’ is above the law, and that they will be brought to justice. Human beings are not chattel to be exploited for sex and sadistically abused, and anyone who thinks otherwise can expect to find themselves in handcuffs and facing federal prosecution like these defendants,” he added.

“For many years, Howard Rubin and Jennifer Powers allegedly spent at least one million dollars to finance the commercial sexual torture of multiple women via a national trafficking network. The defendants allegedly exploited Rubin’s status to ensnare their prospective victims and forced them to endure unthinkable physical trauma before silencing any outcries with threats of legal recourse,” stated FBI Assistant Director in Charge Christopher G. Raia.

“The FBI will continue to apprehend any trafficker who sexually abuses others for twisted gratification,” he added.

“This was not a one-man show. While Rubin dehumanized these women with abhorrent sexual acts, Powers is alleged to have run the day-to-day operations of the enterprise and got paid generously for her efforts,” said Harry T. Chavis, Jr., IRS investigative special agent in charge.
