The 71-year-old American admitted masterminding a massive "Ponzi" pyramid scheme that duped thousands of investors.
Madoff, who previously enjoyed a respected, high-profile Wall Street career, faces the prospect of spending the rest of his life behind bars.

He pleaded guilty in a New York court in March to 11 charges of fraud, perjury and false reporting.
The financier, a former chairman of the Nasdaq stock exchange, apologised for his actions, claiming the fraud began in the 1990s in response to the pain of recession.
He told the court he was "deeply sorry and ashamed" about his crimes.
Madoff and his wife Ruth lived a life of luxury, with homes in Manhattan, the Hamptons and Palm Beach, Florida.
