A school district near Cleveland has canceled Monday's classes because vandals deflated tires on most of the school buses.
Madison Local Schools Superintendent Roger Goudy tells Cleveland television stations WJW and WKYC that about three-quarters of the district's 41 buses were found in a bus garage with air let out of their tires.
Officials say by the time the discovery was made it was too late to get the buses ready for Monday morning.
Police are investigating.
The district about 40 miles northeast of Cleveland has 3,700 students attending three elementary schools, one middle school and one high school.
