Cincinnati City Councilman P.G. Sittenfeld was arrested by FBI agents on Thursday and charged with accepting bribes while in office.

First elected in 2011, the Democratic councilman was the presumptive front-runner in next year’s mayoral election, according to the Cincinnati Enquirer. Charged with bribery, wire fraud, and attempted extortion, Sittenfeld is now the third member of the city council to be arrested on charges related to bribery.
