Officials say inert explosives training material was found on a Virginia school bus a week after the CIA used it in a police dog exercise.
Loudon County spokesman Kraig Troxell says in an email that the material was found Thursday inside the engine compartment of a public school bus in a Virginia suburb of Washington during routine maintenance.
Troxell says the CIA conducted the training from March 21 to 24 at a school in Ashburn, Virginia, during spring break. He says the bus was in service Monday and Tuesday.
The CIA says in a statement that the material was inadvertently left by the agency’s K-9 unit and it did not pose a danger to passengers.
