SAN FRANCISCO (AP) - The FBI investigation that led to the arrest of a prominent California politician was launched three years ago.
Court documents show that's when state Sen. Leland Yee's chief fundraiser was introduced to an undercover FBI agent posing as an associate of Raymond "Shrimp Boy" Chow, an ex-convict who claimed to have turned his life around as a community activist.
The FBI was working to infiltrate the Chinatown fraternal group controlled by Chow and thought to be a front for an Asian gang. Chow introduced Yee's aide Keith Jackson to the agent in May 2011.
Court documents say Jackson eventually led Yee to Chow.
On Wednesday, Yee, Chow and two dozen others were charged with a wide-range of crimes.
