CHICAGO (CBS) — At least ten children were taken to the hospital as a precaution Tuesday night, after wait staff at a Little Village restaurant mistakenly served alcohol, but police said none of the kids had any alcohol in their system.

CBS 2’s Susanna Song reports the children were at a birthday party at the Home Run Inn pizza restaurant at 31st and Kildare around 9:30 p.m. Tuesday.

They ordered fruit punch with their pizza, but their server accidentally brought them punch spiked with alcohol. Police said the server made a mistake with their order.

Police sources said at least one child drank the punch, and might have shared the drink with others.
