FORT LAUDERDALE, Fla. -

A Fort Lauderdale attorney convicted of conspiracy to commit wire fraud in Scott Rothstein's $1.4 billion Ponzi scheme was sentenced in federal court Thursday.

Douglas Bates, 55, was sentenced by U.S. District Judge Donald M. Middlebrooks to 60 months in prison, two years of supervised release and a $200,000 fine.

According to court documents, while Bates was a partner in the Law Offices of Koppel and Bates, he assisted Rothstein in defrauding certain clients of Rothstein's law firm, Rothstein, Rosenfeldt and Adler.

Prosecutors say Bates drafted fraudulent opinion letters claiming to represent an investment group which had a business plan to invest in confidential settlements involving sexual harassment and/or whistle blower cases, when he did not.

Rothstein is serving a 50-year prison sentence.
