Another school district was forced to alter school plans due to vandals on Tuesday.
The Madison Local School District said it had to go on a two-hour delay after vandals broke into the bus compound, unplugged all the block heaters and flattened the front tires on 17 of the district's 20 school buses.
The district said the vandalism happened sometime after 10:30 p.m. Monday, when a returning bus driver saw that all the buses were plugged in.
School bus diesel engines often need the engine block heaters to start on cold mornings.
A similar incident in Mason last month forced the district to cancel classes for the entire day.
