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. Prosecutors said that 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.
