A nurse at a Utah hospital was assaulted by a police officer last month after declining to allow him to obtain a sample of an unconscious patient's blood because he had neither a warrant nor the patient's consent, local media reported.
Prosecutors in Utah will consider criminal charges against the officer, an official said on Friday (local time).
Video of the July 26 incident from Salt Lake City police officers' body-worn cameras showed Alex Wubbels, dressed in blue medical scrubs, consulting with colleagues before showing the waiting officers a printout of the University of Utah Hospital's policy on providing blood samples to test for alcohol or drugs.
The patient was a truck driver who was comatose when he was brought to the hospital burns unit after a crash with a vehicle being driven by someone fleeing police, the Deseret News reported.
Ms Wubbels explained to the officers that under the policy, which she said was agreed to by the police department, she would need a warrant, the patient's consent or the patient would need to be under arrest.
"I'm just trying to do what I'm supposed to do, that's all," Ms Wubbels told the officers, noting that they did not meet any of those criteria.
One officer, identified in media reports as Detective Jeff Payne, appeared angered and grabbed at Ms Wubbels before gripping her around her torso. "We're done," Payne said. "You're under arrest."
He then dragged Ms Wubbels outside as she screamed.
"Somebody help me!" Ms Wubbels cried as Payne pushed her against a wall and handcuffed her. "You're assaulting me! Stop! I've done nothing wrong."
Karra Porter, Ms Wubbels' lawyer, said at a news conference on Thursday (local time) where the video was shown that the nurse followed the law and the police were wrong, according to the Deseret News. Ms Wubbels said her first duty was to her patients.
Salt Lake County District Attorney Sim Gill agreed with police that a criminal investigation of the officer is warranted, chief deputy district attorney Jeff Hall said in a telephone interview. He declined to say what charges may be filed.
