COLUMBIA, Tenn. – A Middle Tennessee horseback rider was jailed after being charged with running into a crowd of people at the Mule Day festivities in Columbia. The man, 32, was charged with two counts of reckless endangerment and public intoxication.
According to The Daily Herald of Columbia, witnesses told investigators that the man rode the horse Saturday into a restricted area that had been closed to animal traffic at the county park and was asking pedestrians for beer. A Maury County sheriff's report said the man dismounted and then attempted to get back on, spooking it.
Two people were then hit by the horse, and one required hospital treatment.
Bond was set at $10,500.
