Lincoln police have arrested a woman accused of buying beer kegs for her underaged daughter and 21 of her underaged friends.

Police say the woman was arrested at her home Sunday on suspicion of 22 counts of contributing to the delinquency of a minor, as well as keg registration violations and maintaining a disorderly house.

Police made the arrest before 2 a.m. after an anonymous caller tipped officers to the party.

Police say all 22 minors were ticketed for being minors in possession of alcohol.

A police spokeswoman says there was so much alcohol in the home that police breathalyzers — used to determine blood-alcohol content — recorded 0.03 percent just from being carried inside.
