HALIFAX -- Nova Scotia's police watchdog says a Halifax police officer used reasonable force in attempting to control a woman whose arm was broken as she waited for a psychiatric assessment.

A report by the Serious Incident Response Team says the incident occurred at a Halifax hospital following an arrest in August, 2014.

The 51-year-old woman was taken into custody under the Involuntary Psychiatric Treatment Act after she was found yelling and screaming in the parking lot of a store in the Dartmouth Crossing shopping area.

Investigators say the officer stayed with the woman, who became upset while waiting for medical attention at the hospital.

The report says a hospital video surveillance camera captured the struggle as the officer attempted to control the woman by placing handcuffs on her.

The report says while force was applied, the video confirms the officer's actions were reasonable and there are no grounds to consider charges.
