The head of San Francisco Public Works, which is in charge of cleaning up the city’s feces-filled streets, has been arrested by the FBI on suspicion of public corruption.

San Francisco Public Works Director Mohammed Nuru was arrested Monday alongside Nick Bovis, the owner of a popular sports bar in Fisherman’s Wharf, Lefty O-Doul’s. Sources told NBC Bay Area that Nuru was arrested on suspicion of accepting bribes for airport concession contracts.
