The D.C. finance office’s investigative arm closed dozens of fraud, theft, embezzlement, bribery and other cases in fiscal 2008 during what the branch termed a “particularly challenging year,” given the fallout of the $50 million tax office scandal.

The Office of Integrity and Oversight under Chief Financial Officer Natwar Gandhi opened a record 94 investigations last fiscal year and closed 80, according to a recently completed annual report, obtained by The Examiner through a Freedom of Information Act request.
