Federal prosecutors say one of Wall Street swindler Bernard Madoff's former controllers will plead guilty in New York to conspiracy charges in history's largest Ponzi scheme.
Prosecutors said in a letter to a judge late Tuesday that Irwin Lipkin will plead guilty at a court appearance Thursday.
The letter says the charges include a conspiracy to falsify records in a fraud that started in the early 1970s and ran through December 2008. The charges carry a potential penalty of 10 years in prison.
Lipkin was a controller at Madoff's firm. His lawyer didn't immediately return a call seeking comment Wednesday.
Madoff pleaded guilty in 2009 to stealing billions through the fraud and says he acted alone. He's serving a 150-year prison sentence in Butler, N.C.
