Nova Scotia’s Serious Incident Response Team has cleared Halifax Regional Police of using excessive force after a woman’s arm was broken during her arrest in March.

In a report released Thursday, investigators say on March 20, the 21-year-old woman was threatening to take her own life. Her boyfriend called police around 2:14 p.m. and officers found a note she wrote confirming the boyfriend’s concerns.

She was later found in a stairwell near the Armdale Roundabout and refused to go with police to hospital. Officers tried to arrest her under the Involuntary Psychiatric Treatment Act but she struggled and kicked an officer several times.

The report goes on to say, as another officer tried to put handcuffs on her, he heard a "pop" sound from her arm. An ambulance was called immediately and she was taken to hospital for treatment of a broken upper right arm.

The police watchdog said the woman’s arm was broken unintentionally as the woman struggled with police and no charges should be laid.
