Oakland's embattled Mayor Sheng Thao has had her home raided by the FBI, local media have reported.

The Democrat lawmaker's home on Maiden Lane was raided around 5:30 am PT Thursday, CBS San Francisco reports.

It is unclear why the property was raided, but according to public records, it appears Thao rents the home. 

'The FBI is conducting court authorized law enforcement activity on Maiden Lane. We are unable to provide additional information at this time,' the agency said on Thursday morning. 

A neighbor told ABC7 News that she woke up to authorities banging on her door around 6 am. 

According to a law enforcement source, this raid is just one of four locations in Oakland that will be searched by the FBI. 

A picture of her home was seen surrounded by multiple unmarks, black vehicles parked on the street. 

The FBI also raided the Oakland home of Andy Duong, a prominent Vietnamese businessman. 

Duong and his family own Cal Waste Solutions, a recycling company that has been investigated over laundering campaign contributions to various member of the City Council including Sheng Thao, according to The Oaklandside.

Sources tell DailyMail.com that the mayor's first official trip last year, to Vietnam, was co-sponsored by the Vietnamese American Business Association, which was formed by a member of the Duong family, leading to speculation that the FBI may be investigating allegations of influence peddling.

The raid took place around 5:30 a.m., sources said. It started when two Jeeps pulled up to the mayor's house and several FBI agents in bullet proof vests jumped out. 

They ran to the mayor's door, announced they were FBI. Standing behind a shield, they then kicked the door in. They remained at the house for the next couple hours.
