Prince William County Police are searching for a motorcyclist who apparently disregarded a designated horse crossing, spooked a passing horse and caused it to knock its rider to the ground.
It happened Sunday at a horse crossing on Route 29 in Manassas National Battlefield Park along the Fairfax and Prince William county line.
The injured rider, a Herndon woman who asked not to be identified, said she and a group of other riders were almost across the road when a motorcyclist, passed five other stopped cars, crossed a double yellow line and revved the engine as he drove passed the horses.
One rider was able to stay on the horse, but she fell off when the horse
was forced to jump over some newly laid rock on the side of the road, the injured woman wrote.
She was taken to a nearby hospital where she was treated for whiplash and a sprained ankle and released.
A license plate or a description of the rider wasn't recorded and police are asking riders and motorist to be vigilant, the Herndon resident said.
Other horseback riders mentioned a recent encounter with a motorcyclist who drove between them as they were using the horse crossing as he shouted, they "had no business there," the woman said.
Anyone with information about the Sept. 1 incident is asked to call Prince William County Police and mention case number 13-155-981.
