Loudoun County, Virginia Explosive material was reportedly left on a school bus following K-9 related training exercises. The local sheriff's office reported that the item in question as "a container of an explosive material." The material was found in the engine compartment of the bus during routine maintenance.
The unidentified substance was described by officials as "harmless" as it didn't contain a blasting cap to activate it. The bus apparently made a total of eight trips transporting special needs children to and from school with the explosive substance on board.
County schools, the CIA, the Loudoun County Sheriff's office and the fire marshal's office agreed to suspend the program while a review is conducted to insure this "mistake" will not happen again.
