A federal grand jury has indicted Oakland’s recalled Mayor Sheng Thao, a source with knowledge of the investigation told the Bay Area News Group — a stunning development in a federal public corruption inquiry that touched the highest levels of East Bay’s political class.

After months of maintaining her innocence, recalled Oakland Mayor Sheng Thao is facing criminal charges from a federal grand jury indictment that will be announced Friday morning, according to reports.

Two months after she was recalled as Oakland mayor, Sheng Thao has reportedly been criminally indicted by a federal grand jury, a blow to a city whose voters have made it clear they are fed up with crime and government dysfunction.
