March 29- Michael Steinberg, a portfolio manager at Steve Cohen's 15 billion SAC Capital Advisors, was arrested by the Federal Bureau of Investigation at his home in New York City early Friday morning in connection with a long-running insider trading investigation of the hedge fund, a FBI spokesman said.
The accord "does not preclude the future filing of additional charges against any person, including Steve Cohen, who is not named as a defendant in these cases," George Canellos, acting director of the SEC enforcement division, said on a conference call.
