California authorities on Wednesday said seven people had been arrested and several items, including 46 pounds of methamphetamine and $10,000, were seized following a drug operation that lasted eight months.

The Fresno County Sheriff’s Office in a news release said that they, along with the Drug Enforcement Administration (DEA) and the FBI, carried out the operation. In addition to the methamphetamine and cash, the sheriff’s office said three pounds of processed marijuana and five weapons were also secured, and 211 marijuana plants were “eradicated.”

The November 2017 arrest of David Stuard, 55, kicked off the investigation, the sheriff’s office said. Stuard was taken into custody after heroin, prescription pills and roughly one pound of methamphetamine was allegedly discovered in his vehicle following a traffic stop, according to authorities.
