Police are investigating a batch of brownies that made some students sick at Riley High School in South Bend.

Investigators say the brownies were laced with something, but they didn’t say what they were laced with, according to 95.3 MNC’s reporting partners at ABC 57.

The students face disciplinary action, ABC 57 reported.

Police were also called to Riley High School last week when a 15-year-old student was found with prescription pills.
