The Santa Clara County Sheriff's office announced Tuesday that it will be cracking down on underage drinking throughout the county with a series of operations through June.
Sgt. Don Morrissey said his department has been targeting underage drinking for the past year with two types of sting operations.
In "shoulder tap" operations an undercover officer posing as a minor asks an adult over 21 to purchase an alcoholic beverage for them. In "minor decoy purchase" operations a decoy posing as a minor enters an establishment and attempts to purchase alcohol.
The Sheriff's Office has conducted 109 "shoulder tap" stings and arrested 16 people as a result of the sting this year.
Establishments where clerks sell alcohol to minors can have their licenses revoked by the California Department of Alcoholic Beverage Control.
Individuals who purchase alcohol for a minor can face fines of up to $1,000 and 24 hours of community service, Morrissey said.
