Butler School District officials confirmed an incident that occurred on a school bus Thursday morning.

Assistant Superintendent of Schools Dr. Brian Slamecka said the incident occurred while the bus was on its way to the school, when an intermediate school male student between the grades of 7 and 9 “took a substance he shouldn't have and got sick.”

Slamecka said the incident was not an overdose, as reported elsewhere, however, said the incident is under investigation by the Butler Township Police Department.

Police were unable to be reached for comment.
