A second Salt Lake City police officer has been put on paid leave as authorities investigate the use of force in a nurse's arrest.
The July 26 incident captured on police body-camera video showed Detective Jeff Payne dragging nurse Alex Wubbels from a hospital and handcuffing her after she refused to allow blood to be drawn from an unconscious patient in a car-crash investigation.
The video has caused outrage since it was released Thursday.
Prosecutors have asked for a criminal investigation, prompting the police department to put two officers on paid administrative leave.
The second officer hasn't been formally identified, but officials have said they also were reviewing the conduct of Payne's boss, a lieutenant who reportedly called for the arrest if Wubbels kept interfering.
Nurse arrested for not giving police patient's blood
Police in the US state of Utah have launched an investigation after video footage showed an officer forcibly arresting a nurse for refusing to draw blood from an unconscious patient.
The images captured by a police body cameras and University Hospital in Salt Lake City show Alex Wubbels screaming for help as she is manhandled out of the medical center and handcuffed.
The nurse was detained for around 20 minutes in a police car before being released after administrative staff intervened, according to Suzanne Winchester, a spokeswoman for hospital.
Winchester told AFP blood samples from a patient could be handed over to the police only if the patient had given their consent, was under arrest or there was a warrant.
None of these conditions was met, said Winchester, who added that Wubbels had correctly followed protocol.
"This is very out of the ordinary. Everybody was very shocked - it was upsetting for our staff," she added.
The incident unfolded on July 26, but the video was only made public on Thursday at a news conference held by Wubbels.
"Stop, stop - I've done nothing wrong... This is crazy, please sir, you're hurting me," she is seen pleading as she is frogmarched to a police car.
Wubbels told journalists she felt betrayed and angry at her treatment when she was only trying to keep her patient safe.
Salt Lake City police chief Mike Brown said he was "alarmed" by the footage and that an internal affairs investigation had been launched.
"To date, we have suspended the officer from the blood draw program. We have already replaced our blood draw policy with a new policy," he added.
"All remaining officers on the blood draw program have reviewed, and are operating under the new policy and protocol."
District attorney Sim Gill issued a statement on Facebook calling for a full criminal investigation, however.
"Injustice against one is an injustice against all. Everyone deserves a fair process and institutional accountability is our collective responsibility," he said.
