WATCH: Nurse arrested not letting cops take blood from unconscious patient

Police bodycam video from July 26, 2017, shows Utah nurse Alex Wubbels being arrested after she refused to take blood from an unconscious patient -- who had been in a collision that left another driver dead.

Salt Lake City police demanded she take a blood sample to determine if the patient was under the influence. After explaining to the detective that the police needed a warrant, consent from the unconscious patient or that the patient needed to be under arrest before the blood sample could be drawn, Wubbels was arrested.

The nurse was released later without charges. The incident is now the subject of an internal investigation.
