Rochester Police Chief David Smith says this week's encounter between a police investigator and an EMT is deeply concerning, and he told the Department's Professional Standards Section to begin an internal investigation.
The investigator has been assigned to desk duty.
The encounter happened Monday in the ambulance bay at Strong Hospital.
An EMT hit the investigator's car with her door while unloading a patient.
Sources say the investigator demanded the EMT's license, but she insisted on getting the patient inside first.
The investigator is seen on security video pulling the EMT's arm behind her back, cuffing her, and taking her to a police car.
Police and EMT supervisors were called to the scene.
The EMT was released without charges.
