The sheriff's office made 21 arrests of adults in three February stings that visited 44 liquor stores or markets with minors attempting to buy alcohol.
Minors supervised by law enforcement tried to buy booze in the store or loitered outside a store and asked adults to buy them alcohol, according to a Contra Costa County Sheriff's Office press release from public information officer Jimmy Lee.
Seventeen adults were charged with selling alcohol to minors, and four were arrested for buying alcohol for minors, Lee said. The arrest of one adult resulted in a further felony charge of possession of methamphetamine, carrying a concealed weapon and possession of burglary tools, police said.
The sheriff's office conducted the decoy operations in conjunction with the California Department of Alcoholic Beverage Control. See the sheriff's office news release attached to this article.
