Los Angeles City Councilman Mark Ridley-Thomas and the former dean of USC’s School of Social Work have been indicted on federal corruption charges alleging a bribery scheme stemming from Ridley-Thomas’ time serving on the county Board of Supervisors, prosecutors announced Wednesday.

Prosecutors contend a Ridley-Thomas relative received substantial benefits from the university in exchange for Ridley-Thomas supporting county contracts and lucrative contract amendments with the university while he served on the county board.

The 20-count indictment filed in Los Angeles federal court alleges that Ridley-Thomas conspired with Marilyn Louise Flynn to provide the relative with graduate school admission, a full-tuition scholarship, a paid professorship, and a mechanism to funnel Ridley-Thomas campaign funds through the university to a nonprofit to be operated by the relative.
