Saskatoon police used a stun gun early this morning to subdue a woman who was threatening to harm herself with a butcher knife.

It's the first time officers have used the device since they were issued in December.

The 26-year-old woman is now facing charges of assaulting a police officer.

' I think lethal force may have been an option there.'- Chief Cli ve Weighill

Chief Clive Weighill told CBC that, given the circumstances, the woman is lucky to be alive today.

"When a police officer is being approached by somebody with a knife in a hysterical situation I think lethal force may have been an option there," he said.

Police said in a news release that it started when officers were called to Edinburgh Place just before 2 a.m. CST with reports a woman threatening to harm herself.

When they arrived, the woman advanced towards one of the officers with a butcher knife. The conducted energy weapon was used after officers attempted unsuccessfully to disarm the woman.

Police were then able to arrest her. Paramedics at the scene took her to hospital as a precaution.

The incident will be examined by the Use of Force Review Board and the Saskatchewan Police Commission.
