Nathan Chasing Horse, an actor in the Oscar-winning film "Dances With Wolves," was arrested by Las Vegas police on Tuesday for allegedly sexually assaulting young Indigenous girls over two decades. SWAT officers were seen outside his two-story home in North Las Vegas, which he shares with his five wives, and police searched the property as part of the investigation. Chasing Horse is known for his role in the 1990 Kevin Costner film and as a so-called medicine man who performed spiritual ceremonies.
