KANSAS CITY (AP) — A south Kansas City school district says police are investigating a report that at least one student became ill after eating marijuana-laced brownies.

The Hickman Mills district said in a statement Monday the incident happened in late March at Hickman Mills Freshman Center.

Assistant principal John Miller said a student complained March 28 that she felt strange after eating a brownie given to her by another student.

Another student said she felt fine after taking a bite of the same brownie. And Miller said the girl accused of having the brownies denied they were laced with anything.

The school nurse were checked the students, who were then sent home. Miller reported the incident to the Missouri Division of Family Services.
