This is how diplomacy loosely works: visiting diplomats accused of a serious crime have the option of facing the charges locally, facing the charges under their home jurisdiction, or leaving the country either voluntarily or by being expelled. The one exception to this is if the visiting country waves diplomatic immunity, which generally only happens if someone was doing something outside of the nature of normal activities of living and working there. I know it might not seem fair, but sometimes the smooth workings of international diplomacy is more important than justice for an individual crime. (The expulsion option prevents diplomats from using this as a loophole to repeatedly commit crimes)
