In America, it is illegal to refuse anyone who presents at an ER with Emergency Medical care. See the Emergency Treatment and Active Lab or Act (EMTALA). This is true regardless of whether a criminal investigation is in progress or not. If you are asking, "When in police custody (arrested or detained), is it illegal to withold emergency medical treatment?", that answer too is yes. When you're in custody, it becomes the responsibility of the detaining agency to make sure you receive necessary (albeit sometimesminimal) care.
