NEW YORK -- A boyish-looking entrepreneur who became the new face of corporate greed when he jacked up the price of a lifesaving drug fiftyfold was led away in handcuffs by the FBI on unrelated fraud charges Thursday in a scene that left more than a few Americans gleeful.

Martin Shkreli, a 32-year-old former hedge fund manager and relentless self-promoter who has called himself "the world's most eligible bachelor" on Twitter, was arrested in a gray hoodie and taken into federal court in Brooklyn, where he pleaded not guilty. He was released on $5 million bail.

If convicted, he could get up to 20 years in prison. He left court without speaking to reporters. His attorneys had no immediate comment.

Online, many people took delight in his arrest, calling him a greedy, arrogant "punk" who gave capitalism a bad name and got what was coming to him. Some cracked jokes about lawyers jacking up their hourly fees 5,000 percent to defend him in his hour of need.

Prosecutors said between 2009 and 2014, Shkreli lost some of his hedge fund investors' money through bad trades, then looted Retrophin, a pharmaceutical company where he was CEO, for $11 million to pay back his disgruntled clients.

Shkreli "engaged in multiple schemes to ensnare investors through a web of lies and deceit," U.S. Attorney Robert Capers said in a statement.
