Deputies are investigating after two buses in Greenville County were hit by what they think were rocks.
It happened Friday afternoon on Highway 414 at Wilton Way when a bus driver heard a loud pop come from the driver's side window. School district officials say the driver thought the bus may have been shot at by a passing vehicle.
A few minutes later, another nearby bus driver also heard a loud pop. Both drivers noticed a blue truck at the time of the noise, according to investigators.
Both buses were carrying students from Blue Ridge Middle and High School.
The Greenville County Sheriff's Office was called to the scene. Out of caution, the buses were parked while deputies investigated.
They say it appears both buses were hit by rocks thrown from a passing vehicle.
All buses continued their normal routes about 15 minutes later. The window on the first bus was shattered, but no injuries were reported. The investigation continues.
