MENOMONEE FALLS -- Nearly two dozen people were nabbed for underage drinking at a Menomonee Falls restaurant. It all unfolded at Su Casa Grandeafter restaurant hours Friday morning, May 31.

The doors of Su Casa Grande were already closed to the public for the night.

"So our officers responded along with some deputies from the Waukesha County Sheriff's Department to investigate," Knop said.

Police said "approximately 50 people between the ages of 16 and 22" were in the restaurant.

"Twenty-three of those people were found to be under the age of 21 and had been drinking," Knop said.

All 23 were cited. Underage drinking tickets in Menomonee Falls can range from $98 to $854. Authorities would not say how the group got into the restaurant after hours. But they did say how they got home -- a call home.

"We arranged for parents of those who were cited and had been drinking underage to come to that location and take custody of their children," Knop said.

In the meantime, Capt. Knop said the bust should serve to remind teens and parents of the consequences that can come from underage drinking.

"Everything from overdoses, to reckless driving, to disorderly conduct, to traffic crashes, causing damage, injury, maybe even death," Knop said.

A restaurant manager FOX6 News spoke with on Monday, June 3 had no comment.
