Solomon Dwek is scheduled to appear in federal court on Oct. 18 to receive a sentence of nine to 11 years for a $50 million bank fraud case that led to his decision to help the government.

The Star-Ledger of Newark reports Solomon Dwek's lawyer claims the former real estate investor has bipolar disorder and chronic high anxiety.

In court filings, his lawyer says federal prosecutors will also ask for a shorter sentence.

Solomon Dwek's assistance helped authorities arrest dozens and elected officials, five rabbis and a black-market kidney broker.
