Rothstein, who had fled to Morocco in late October but returned in early November, is expected to appear at a magistrate hearing to face the RICO conspiracy charge at the federal courthouse in Fort Lauderdale.
While under federal watch in November, Rothstein cooperated with prosecutors and provided them with details of his Ponzi scheme, involving the sale of fabricated legal settlements to wealthy investors.FBI and IRS agents also raided his Fort Lauderdale law office and seized his waterfront home and other assets.
Rothstein could not be reached for comment, and his attorney, Marc Nurik, declined to say anything about his client's imminent arrest.
``Scott intends to see that all legitimate investors get paid back,'' Nurik said late Monday. ``Exactly how that's going to be done remains to be seen. He is sincere in his intent.''
Rothstein, 47, is likely to plead guilty soon while he is in custody. The U.S. attorney's office, meanwhile, will convene a grand jury to consider criminal charges against Rothstein's alleged co-conspirators -- including possibly former employees of his now-defunct firm.
