A 26-year-old man was arrested after State Police received reports that he was harassing several horse riders on Union Road in the south central Massachusetts town of Holland.

Francis Reilly of Holland revved the engine of his white pickup truck and drove past three riders on horseback at about 8:15 p.m on Sunday, State Police said. Reilly honked his horn and made contact with the tail of one of the horses, causing it to buck and run into another horse, according to State Police.

The rider then fell off of that horse and onto the pavement, State Police said. No information on the rider’s condition was available Tuesday night.
