The accusations against Dominique Strauss-Kahn become more alarming with each fresh episode.

On Friday, news emerged that French investigators are looking into allegations that Strauss-Kahn, 63, the former chief of the International Monetary Fund, might have been involved in a rape at a sex party in the W Hotel in Washington. In the New York Times, Maia de la Baume reports from Paris that the prosecutor’s office has submitted new evidence about Strauss-Kahn’s involvement in a prostitution ring in France that supplied women to luxury hotel guests in the city of Lille. That information reportedly connects Strauss-Kahn to the W Hotel incident.

Strauss-Kahn’s lawyers strongly deny the allegation, calling it part of a “lynching campaign,” the AP reported.

Strauss-Kahn was charged in March with “aggravated procurement in an organized gang” – commonly known as pimping. Along with Strauss-Kahn, three executives of the Hotel Carlton, a police official and a lawyer have been charged.

The new accusations against DSK, as he is known in France, are based on testimony by two Belgian prostitutes.

DSK is in hot water on many fronts – all of which involve sex in various cities.

As my colleague Delia Lloyd reported this week, a Bronx judge ruled that a civil suit brought by Nafissatou Diallo could proceed and rejected DSK’s claim of diplomatic immunity. Diallo was a maid at the Sofitel Hotel in New York City. She, too, accused DSK of rape. The criminal case against DSK was dropped because of questions surrounding Diallo’s credibility.

But that drama cost DSK his job as he was forced to resign in 2010 from the IMF, where he had been managing director since 2007. He also had to abandon hopes of running for the French presidency as the socialist candidate.

Unlike in the United States, visiting a prostitute is not illegal in France, but it is illegal to supply others with prostitutes. Rape, however, is illegal in France and the United States.

In the book “Men Who Rape: The Psychology Of The Offender” by A. Nicholas Groth and H. Jean Birnbaum, the authors outline the patterns of rape of which one variation is gang rape. They write, “In cases of rape involving a single offender, we are faced with the dynamics of the individual, but, in cases of gang rape, these dynamics become compounded by the interactions of the co-offenders.”

They add that sexual gratification is not the motive or reward in either individual or gang rapes, but rather in gang rape, the motive is often simply camaraderie.

So far, Strauss-Kahn, who was a corporate lawyer and academic before his stint at the IMF, has dodged a lot of trouble – from charges being dropped in the Diallo case to the statute of limitations running out in the case of Tristane Banon, a French writer who accused DSK of a rape that accused nearly a decade ago. Prosecutors said that there was evidence that DSK sexually assaulted Banon.

Prosecutors now may expand their investigation in Lille amid this week’s new allegations. Will Strauss-Kahn’s luck run out?
