A major human trafficking operation in Placer County resulted in nearly two dozen men busted for alleged sex solicitation, drug possession and more. Undercover agents with the Placer County Sheriff’s Office Operations Unit conducted a two-day sting where they contacted sex buyers throughout the county. The operation busted 21 men cited for soliciting prostitution, the sheriff’s office said. During the sting, agents contacted individuals who were “attempting to purchase sex, sometimes referred to as ‘johns.’”
