A resident looks on as a U.S. Federal Bureau of Investigation agent carries boxes from the Ghee Kung Tong building, which houses the Chinese Freemasons, in the Chinatown neighborhood in San Francisco, California March 26, 2014. California state Senator Leland Yee was arrested on Wednesday as federal investigators conducted public corruption raids across California, shaking up the election season in the nation's most populous state. In addition, federal authorities arrested Raymond "Shrimp Boy" Chow, FBI spokesman Peter Lee said, referring to a figure previously convicted in a San Francisco organized crime probe. Chow once served as head of the Chinese Freemasons, who own the Ghee Kung Tong Supreme Lodge, now being searched by investigators in connection to the case.
