ST LOUIS (LALATE) – Anthony Chiasson, Todd Newman, and Jon Horvath have been arrested for alleged insider trading, claims a new report. Anthony Chiasson (Level Global Investors), Todd Newman (Diamondback Capital Management), and Jon Horvath (Sigma Capital Management) are allegedly among the growing number of defendants added to the trading probe by officials. When sought for comment, attorneys for the three individuals would not respond to requests by local news.

Two years ago, federal investigators raided four hedge firms. Those raids reportedly widened the initial investigation. Level Global, Diamondback, Loch Capital Management and Barai Capital Management were raided by the FBI in winter 2010. At the time, Rajat Gupta, formerly of McKinsey, Goldman Sachs, and Procter & Gamble was charged. He eventually was convicted last May of fraud and conspiracy charges. Gupta is now serving an 11 year prison term.
