Police say employees of four Long Island businesses have been arrested in an underage drinking sting.

Suffolk County police sent a volunteer under the age of 21 to four businesses Friday night and had the person attempt to buy alcohol.

Police say employees at all four businesses agreed to sell alcohol to the volunteer.

They were two delis in Greenlawn and a convenience store and a tavern in Huntington Station.

The four employees were issued tickets and ordered to appear at First District Court in Central Islip on July 18.
