OMAHA, Neb. (AP) — Officials for a public school district in Omaha say a high school student brought brownies laced with a laxative to school.

Millard Public Schools spokeswoman Rebecca Kleeman says the student brought the brownies to Millard North High School on Nov. 25.

Several students ate the brownies and got sick.

Kleeman says the student was ticketed by police on suspicion of assault and was disciplined by the district for violating its code of conduct. She did not elaborate.
