A portfolio manager for the hedge fund operator SAC Capital Advisors has pleaded not guilty to federal charges in an insider trading probe.
The FBI arrested Michael Steinberg at 6 a.m. Friday at his home in New York City.
His attorney says in a statement that Steinberg "did absolutely nothing wrong."
Attorney Barry H. Berke says Steinberg was "caught in the crossfire of aggressive investigations" into other people's activities.
At least four other people associated with the Stamford, Conn.-based firm have been arrested over a period of about four years.
On March 15, the Securities and Exchange Commission said that two affiliates of SAC Capital Advisors would pay more than $614 million in what federal regulators called the largest insider trading settlement ever. The settlement is subject to court approval.
