Federal prosecutors have indicted a third former Ogilvy & Mather executive for allegedly overbilling the US government, it has emerged.

Peter Chrisanthopoulos, one-time president of broadcasting and programming at O&M, pleaded guilty after being indicted last month in connection with the agency's work for the White House Office of National Drug Control Policy. Chrisanthopoulos admitted altering his timesheets.

This latest development in the case has been kept quiet until now, and emerged only after court paperwork was accidentally unsealed. The indictment was first reported by the New York Daily News, then later confirmed by an unnamed source connected with the investigation.

Early last month, two other ex-O&M executives were charged with inflating the WPP Group agency's labor costs on the ONDCP account [WAMN: 07-Jan-04]. Thomas Early (quondam financial director) and Shona Seifert (former executive group director, now president of TBWA/Chiat/Day's office in New York) both pleaded not-guilty.

After leaving O&M, Chrisanthopoulos moved to Californian broadcaster Pappas Telecasting Group, where he became president and chief operating officer. He resigned those positions last month.
