Federal officials are accusing a California state senator of conspiracy to deal firearms and wire fraud.
The allegations against State Sen. Leland Yee were outlined in an FBI affidavit in support of a criminal complaint against Yee and 25 other people. The affidavit was unsealed Wednesday, as Yee was scheduled to appear in court.
Also named in the affidavit is Raymond Chow. Chow, who is also known as "Shrimp Boy," was the former leader of a Chinese criminal organization with ties to Hong Kong.
Chow is accused of money laundering, conspiracy to receive and transport stolen property and conspiracy to traffic contraband cigarettes.
He and Yee were arrested earlier in the day during a series of raids by the FBI in Sacramento and the San Francisco Bay Area.
Yee represents western San Francisco and much of San Mateo County.
