NEW YORK — The younger brother of Bernard Madoff, who became an icon for financial crime after the economy collapsed in 2008, is poised to plead guilty to criminal charges.

Peter Madoff, 66, was taken into custody at his lawyer’s Manhattan office about 7 a.m. EDT today, according to FBI spokesman J. Peter Donald. The procedure was a prelude to a court appearance scheduled a few hours later.

The plea is to take place at same Manhattan courthouse where his now 74-year-old brother was taken away in handcuffs after he was condemned to 150 years in prison in 2009 for cheating thousands of people of billions of dollars. They are the only Madoff family members to face criminal charges.

The proceeding in which Madoff is agreeing to serve 10 years in prison and surrender his assets will let investigators show what they have learned about the largest Ponzi scheme ever prosecuted in U.S. history since Bernard Madoff revealed in December 2008 that his investment business was a sham.
