A Loudoun County school bus transported 26 students while unknowingly also transporting explosive material, according to a school official.
Investigators on the scene at the Loudoun County Public School Transportation Center near Leesburg say that suspected explosive material found on a school bus this afternoon was left there as part of a training exercise.
Wayde Byard, public information officer for Loudoun County Public Schools, confirmed that the material was explosive, but said there were no detonators attached and the material could not be detonated by normal activity.
Byard said the bus had been in service twice, on Monday and Tuesday, since the material was placed aboard last weekend. The bus transported 26 children from Pinebrook and Buffalo Trail elementary schools and Rock Ridge High School. The school system has begun attempting to contact and notify affected families.
He would not confirm where the material was planted, but he did say it was not located in the cabin of the bus.
Loudoun County Sheriff’s Office Public Information Officer Kraig Troxell said the training materials were left there by another agency. As a precaution, the area and other buses were searched.
The Loudoun County Fire Marshal’s Office is investigating.
This is a breaking story. More information will be reported as it becomes available.
