Police and sheriff's deputies in Stanislaus County cited nearly three dozen people Saturday in an undercover operation targeting adults willing to buy alcohol for people under age 21, law enforcement officials said.
The Stanislaus County sting was part of a multicounty operation in Northern California that netted 80 citations for selling or furnishing alcoholic beverages to minors and involved the Modesto Police Department, the state Department of Alcoholic Beverage Control and 14 other law enforcement agencies.
Additionally, 18 people were arrested on suspicion of other violations, including illegal drugs, being drunk in public, having an open container and parole violations, according to a beverage control news release.
The operation aims to curb minors' access to alcohol and prevent alcohol-related problems on St. Patrick's Day, which is Wednesday.
