Over a year after the federal authorities raided hedge funds, the FBI has arrested three men as part of its insider trading investigation, including a Manhattan resident who wasn't home when they went to his home this morning.

According to Dealbook, "Anthony R. Chiasson, co-founder of the Level Global hedge fund, surrendered in New York after F.B.I. agents went to his apartment in Manhattan but he was not home, the person briefed on the matter said." (The Wall Street Journal says the agents "entered his apartment building at East 96th Street and Madison Avenue at 5:58 a.m. They emerged about 10 minutes later and left before 6:30 a.m.")

The WSJ reports, "The arrests Wednesday reflect a broadening of the government's long-running investigation of employees of public companies sharing confidential information with hedge-fund analysts and traders. The government has monitored hundreds of conversations on wiretaps, and has sought cooperation from a wide range of public-company employees and money managers as the probe has widened." Bloomberg News now says seven people have been charged, but their names have not been revealed.
