Former IMF chief, Dominique Strauss-Kahn, was released from prison in the northern French city of Lille during questioning by police over alleged involvement in a prostitution ring, reports the Wall Street Journal.
Strauss-Kahn, 62, was summoned by investigators Tuesday morning to answer questions about an alleged prostitution ring that occured in Belgium and France.
The Associated Press reported that the former IMF chief and one time French presidential hopeful, was held overnight in a cell during two days of questioning.
French law allows police to hold a suspect for 96 hours with the approval of a judge.
Strauss-Kahn may be called back for further questioning in March or charged, the Financial Post reported a French judicial spokeswoman said.
During the questioning, according to the Daily Mail, Strauss-Kahn admits taking part in orgies and said he had an 'uninhibited sex life', but that he 'never paid a centime" for it. "I have a horror of prostitutes and pimping," he is reported as saying.
Though prostitution is legal in France, investigators are trying to determine whether the women had been paid with embezzled funds or company expense accounts, according to The New York Times.
Eight men have already been arrested in the investigation that has become known as the "Carlton affair, which according to the BBC, was named after the hotel in Lille hotel where clients met the call girls.
These allegations are the latest in a series of similar accusations of Strauss-Kahn's sexual misconduct.
Strauss-Kahn resigned from his position at the IMF last May after accusations by a New York City hotel housekeeper that he had raped her. The case was dismissed but he later said that he had made mistakes.
Upon his return to France, he was accused by a French writer of attempted rape but was not be arrested due to a three-year statute of limitations, according to The Times.
