A Glen Ellyn junior high student brought chocolate milk mixed with Bailey’s Irish Cream to school as a “joke,” Glen Ellyn police said.

Glen Ellyn Deputy Police Chief Bill Holmer said this week the 13-year-old girl allegedly brought the liquor mixed with chocolate milk to Hadley Junior High School on Dec. 9. Holmer said it’s unclear if any students actually drank the concoction, but it was “given to some other students who claimed to not know what they were given.”

The “kid brought this stuff to school claiming it was meant to be a joke,” Holmer said.

A student at the school informed staff about the drink, who interviewed other students about the incident then called police, Holmer said.

Police worked with the juvenile and her parents “regarding enforcement action,” according to a police report.
