LONDON — Three portfolio managers with an SAC Capital Advisors unit in London have left the firm, according to documents filed with a British agency that tracks corporate registrations.

Alidod Shirinbekov, Woei Chan and Paul Crouch left the firm’s SAC Global Investors unit in London on Sept. 26, according to filings with the agency, the Companies House.

The filings did not indicate the circumstances of their departures, and the traders could not be reached Wednesday for comment.

A spokesman for SAC declined to comment.

The traders left shortly after review season at the SAC Global unit. It was unclear whether they left voluntarily.

SAC, the hedge fund founded by Steven A. Cohen, is facing criminal charges in the United States, where employees of the firm are accused of engaging in “rampant insider trading” for more than a decade.

Cohen has been charged separately by the Securities and Exchange Commission in a civil administrative action with failing to supervise two employees charged criminally with insider trading. Cohen has not been charged criminally.

SAC and Cohen have denied any wrongdoing.

Bloomberg News reported the departures earlier.
