(KNBC-TV) The San Bernardino County Sheriff ordered an internal investigation Thursday into an arrest caught on NBC Los Angeles' NewsChopper4 video that showed deputies beating a suspect when they caught up to him following a wild desert chase on horseback.
Aerial footage showed the man falling off the horse he was suspected of stealing during the pursuit in San Bernardino County Thursday afternoon.
He then appeared to be stunned with a Taser by a sheriff's deputy and fall to the ground with his arms outstretched. Two deputies immediately descended on him and began punching him in the head and kneeing him in the groin, according to the footage.
