Police and school officials in the Centerville district are looking into an incident Wednesday afternoon in which a window was busted out of a school bus while students were being taken home.

No one was injured when the window broke at approximately 4 p.m. on a bus transporting Tower Heights Middle School students, according to police and school officials.

Some parents called the News Center 7 newsroom concerned that something was thrown or shot at the bus. However, investigators quickly determined that the window was broken out from inside the bus, possibly from “horse play” among the students, said John Davis, spokesman for Centerville police.

The children were off-loaded and taken home on another bus, said Centerville schools Superintendent Tom Henderson.

Parents were also contacted by the district and informed of the situation, Henderson said.
