Bomb-making material found on Loudoun County school bus

Loudoun County school officials confirmed to FOX 5 that bomb-making material was found on a school bus Wednesday afternoon.

School officials and the CIA said explosive training material was inadvertently left on the bus at Briar Woods High School in Ashburn during a K-9 training exercise conducted from March 21-24 when students were off on Spring Break.

The material was located Wednesday inside the engine compartment of the bus during routine maintenance work. The CIA said the material is stable and did not pose a danger to any student who were transported on the bus this week.

Since the start of this week, the school bus drove on eight runs to three different schools, picking up students on those routes. Their parents have been notified.

Statement from CIA on K-9 Training Incident in Loudoun County:

CIA K-9 units regularly participate in training with K-9 units from federal, state and local law enforcement agencies in the Washington Metropolitan Area.

Last week, a CIA K-9 unit conducted a routine training exercise with law enforcement officials in Loudoun County, VA. During the exercise, explosive training material was inadvertently left by the CIA K-9 unit in one of the buses used in the exercise.

On Wednesday, March 30, CIA was notified that the explosive training material was found when the bus was undergoing routine maintenance. CIA coordinated closely with local authorities and recovered the training material. According to Loudoun County officials, the bus transported students on March 28 and 29. CIA and Loudoun County explosives experts have confirmed that the training material did not pose a danger to passengers on the bus.

To prevent such incidents from happening again, CIA has taken immediate steps to strengthen inventory and control procedures in its K-9 program. CIA will also conduct a thorough and independent review of CIA's K-9 training program. CIA performed a full inventory this morning and accounted for all the explosive training material used in the K-9 training program.
