Officials say a person died Wednesday night after treatment at Albany Medical Center Hospital.
Albany Med officials said the person - whom they said displayed aggressive and belligerent behavior - was brought into the emergency department by Albany police and an ambulance crew.
Hospital officials also said that, under federal privacy laws, it could not disclose any health information - including physical description - of the patient.
Staffers tried several times to calm down the person.
"On the order of a physician, and with the agreement of the patient, a medication to calm the patient was administered," read a statement issued by Albany Med. "Despite these efforts, it became necessary to attempt to restrain the patient in an effort to prevent injury to staff, others in the emergency department, or to the patient."
Albany Med staffers and the patient both were hurt when staffers applied restraints.
"Immediately after the patient was restrained and could be re-evaluated, it was determined that the patient had stopped breathing and had no pulse," read the press statement.
Revival efforts failed. The patient was pronounced dead.
Hospital officials say the cause of death has not been determined. An autopsy and toxicology tests will be conducted.
Staffers involved in the incident have been placed on administrative leave.
