The IRS Criminal Investigations of Northern California handed out a search warrant and inspected the Taqueria El Balazo restaurant at 480 San Ramon Valley Blvd., said IRS Public Information Officer Arlette Lee. It has also obtained search warrants for El Balazo eateries in San Ramon and Pleasanton.
"We are doing search warrants at their locations," she said.
She said the affidavits for the search warrants are sealed and could not reveal their contents.
"I can't discuss (them)," Lee said.
She said the IRS works alongside the U.S. Attorney's Office, which would determine whether to unseal the affidavits and make them public.
Managers of the Taqueria El Balazo in Danville could not be reached for comment by press time.
The IRS Criminal Investigations of Northern California is headquartered in the Federal Building in Oakland.
