Former IMF chief Dominique Strauss-Kahn has been handed preliminary charges alleging he was involved in a French prostitution ring.
Investigating judges have questioned Strauss-Kahn for several hours.
Lawyer Richard Malka told reporters after Strauss-Kahn left that he was accused of procuring prostitutes and involvement in an "organised gang".
Mr Malka said Strauss-Kahn denies wrongdoing. The lawyer also said it is wrong to prosecute Strauss-Kahn for "simple libertine activity".
Under French law, preliminary charges mean authorities have reason to believe a crime was committed but allow more time for investigation.
Strauss-Kahn quit the International Monetary Fund after a New York hotel maid said he sexually assaulted her in May.
The charges were later dropped.
