HARRISBURG, Pa. - Pennsylvania's state employee pension fund is looking for help in dealing with unspecified allegations against its chief investment officer, who recently retired after being placed on leave.

The State Employees' Retirement Board voted Wednesday to authorize its auditors to recommend "independent professional services" to assess the allegations against investment manager Tony Clark.

The outside help will also review the "due diligence" procedures the pension system uses when it is considering making investments.

The agency hasn't disclosed the nature of the claims against Clark, but urged people not to draw conclusions before an independent investigation is complete.

Calls on Tuesday and Wednesday to a Virginia phone number listed in Clark's name have gone unanswered.

The pension fund is also starting to look for a replacement for Clark.
