State Department of Justice officials said agents took down a drug trafficking organization on Wednesday, arresting 10 people.
A four-month investigation led to the arrests. The alleged drug trafficking organization targeted by the DOJ's Bureau of Narcotic Enforcement spread over six counties, including Sacramento, Placer and El Dorado.
Major marijuana grow sites were found in El Dorado, Shasta and Napa counties. Thousands of plants, several firearms and two pounds of crystal methamphetamine were seized.
Search warrants were issued, including seven for structures in Placer, Sacramento and Butte counties, a DOJ spokeswoman said.
