WINONA, Minn. — A female with a youngish voice called police to report that minors were being served at a downtown bar. She hung up before leaving her name. This was about 12:15 a.m. Officers went to the bar, in the 100 block of West Third Street, and found no under-age customers. The bartender said, however, that he had refused to serve girl whose ID showed she was 20 — too young to drink legally. He said she huffed out, saying she would get even.
