HALIFAX -- Nova Scotia's Serious Incident Response Team says there was no excessive force used in a case involving a woman who suffered a broken arm during an arrest by Halifax police.

A report by the police watchdog says the incident occurred March 20 after officers received a call from the 21-year-old woman's boyfriend who said she was threatening to take her own life.

The woman was found in a restaurant building near the Armdale roundabout, but refused to go to hospital with the officers who then attempted to arrest her under the Involuntary Psychiatric Treatment Act.

The report says a struggle ensued during which one of the officers was kicked several times before the other succeeded in getting the woman into handcuffs, but not before a "pop" was heard from her arm.

The woman was taken to hospital and treated for a broken upper right arm.

The investigation concluded the woman's arm was broken unintentionally, so no charges are warranted against either of the two officers involved.
