New York prosecutors say Wall Street swindler Bernard Madoff's brother deserves to spend 10 years in prison for his role in Madoff's crimes.

Prosecutors say in a sentencing brief filed late Thursday the decade Peter Madoff agreed to serve when he pleaded guilty earlier this year is appropriate. The sentencing is scheduled to take place in Manhattan federal court Dec. 20.

The 66-year-old Peter Madoff claimed at his June plea to conspiracy and falsifying records charges he was a victim of his brother. The government says at least one victim among thousands harmed by the $20 billion fraud wants to speak at the sentencing.

Bernard Madoff pleaded guilty to fraud charges and is serving 150 years in prison in Butner, North Carolina Lawyers for Peter Madoff haven't commented.
