Police sent people under the age of 21 into 15 area businesses on Monday night as part of a crack down on illegal alcohol sales.
Deputy Police Chief Wally Tower says the underage customers bought liquor at Wal-Mart, China Coast Restaurant and Mr. Mike’s Convenience Store.
All three businesses were issued summonses.
Tower says they now face fines of $50 to $1,500.
Their liquor licenses are also subject to a review by the city.
Tower says this is the first time police have conducted an operation like this, thanks to a government grant to pay officers overtime to monitor liquor sales at businesses.
