U.S. District Judge Denny Chin denied bail for Madoff, 70, and ordered him to jail, noting that he had the means to flee and an incentive to do so because of his age.

Madoff spoke softly but firmly to the judge as he pleaded guilty to 11 charges in his first public comments about his crimes since the scandal broke in early December.

"I am actually grateful for this opportunity to publicly comment about my crimes, for which I am deeply sorry and ashamed," he said. "As the years went by, I realized my risk and this day would inevitably come. I cannot adequately express how sorry I am for my crimes."

Prosecutors say the disgraced financier, who has spent three months under house arrest in his $7 million Manhattan penthouse, could face a maximum term of 150 years in prison at sentencing June 16.

DeWitt Baker, an investor who attended the hearing and said he lost more than a million dollars with Madoff, called it "fantastic" that Madoff's bail was revoked but belittled the apology.

"I don't think he has a sincere bone in his body," said DeWitt, who added that prison time would be too good for Madoff. "I'd stone him to death," he said. Madoff did not look at any of the three investors who spoke at the hearing, even when one turned in his direction and tried to address him.

The fraud, which prosecutors say may have totaled nearly $65 billion, turned a revered money man into an overnight global disgrace whose name became synonymous with the current economic meltdown.

Madoff described his crimes after he entered a guilty plea to all 11 counts he was charged with, including fraud, perjury, theft from an employee benefit plan, and two counts of international money laundering.

He told the judge that he believed the fraud would be short-term and that he could extricate himself. He implicated no one else, though investigators suspect involvement by relatives and top lieutenants who helped run his operation from its midtown Manhattan headquarters.

The plea came three months after the FBI claimed Madoff admitted to his sons that his once-revered investment fund was all a big lie — a Ponzi scheme that was in the billions of dollars. Since his arrest in December, the scandal has turned the former Nasdaq chairman into a pariah who has worn a bulletproof vest to court.

The scheme evaporated life fortunes, wiped out charities and apparently pushed at least two investors to commit suicide. Victims big and small were swindled by Madoff, from elderly Florida retirees to actors Kevin Bacon and Kyra Sedgwick and Nobel Peace Prize winner Elie Wiesel.
Helicopters circled above the courthouse before the hearing, and federal officers with machine gun-style weapons stood outside as Madoff arrived.

Jilted investors signed in before entering the courtroom on the 24th floor. Richard and Cynthia Friedman turned up to get a glimpse of the man who defrauded them of their life savings of $3 million.

Richard Friedman, an accountant, noticed how well his clients were doing with Madoff and began investing his own money in 1991. He learned it was gone months before he had planned to retire — a plan now on hold.

"I wanted him to see some of the faces of the people he lied to and destroyed," said Cynthia Friedman, 59, of Jericho, N.Y.

After arguments began on whether Madoff should remain free on bail, his lawyer Ira Sorkin described the bail conditions and how Madoff had, "at his wife's own expense," paid for private security at his penthouse.

Loud laughter then erupted among some of the more than 100 spectators crammed into the large courtroom on the 24th floor of the federal courthouse in lower Manhattan. The judge warned the spectators to remain silent.

George Nierenberg, the first of the three investors to speak, approached the podium glaring at Madoff, then said in the financier's direction: "I don't know if you had a chance to turn around and look at the victims."

At the hint of a confrontation, a marshal sitting behind Madoff stood up, and the judge directed Nierenberg to speak directly to the bench.

The courtroom erupted in applause after the judge announced Madoff would go directly to jail. As he was led out of court, a spectator yelled, "Hey, Bernie," but was shushed by investors in court and backed off.

The plea does not end the Madoff saga: Investigators are still undertaking the daunting task of unraveling how he pulled off the fraud for decades without being caught.

Court papers say Madoff generated or had employees generate "tens of thousands of account statements and other documents through the U.S. Postal Service, operating a massive Ponzi scheme," prosecutors said.

The money was never invested, but was used by Madoff, his business and others, prosecutors said.

Authorities said he confessed to his family that he had carried out a $50 billion fraud. In court documents filed Tuesday, prosecutors raised the size of the fraud to $64.8 billion.

Experts say the actual loss was more likely much less and that higher numbers reflect false profits he promised investors. So far, authorities have located about $1 billion for jilted investors.
In addition to prison time, he said Madoff faces mandatory restitution to victims, forfeiture of ill-gotten gains and criminal fines.
