Nez Perce County Commissioner Michael Grow was arrested today on charges of battery and sexual assault. Valley County Sheriff's Lt. Dan Smith said that Grow was vacationing with friends at the Tamarack Resort in Donnelly, Idaho at the beginning of April, when he allegedly assaulted a woman. The victim is an adult female who, according to Smith, knew Grow. After a two week investigation, Valley County deputies issued a warrant for Grow and drove to Nez Perce County to place him under arrest. He is currently being held at the Nez Perce County jail on a $50,000 bond.
