NIAGARA FALLS – A school bus with children on it was struck by a pellet from a BB gun this afternoon at 18th Street and South Avenue.

City Police Superintendent John R. Chella said the shot caused a window to crack but not collapse during a 3 p.m. bus run.

“There were students on the bus, but no one was hurt,” Chella said. “This appears to be a case of criminal mischief.”

Police continue to investigate the incident.

Chella said the children were able to continue home on the same bus.
