A woman was sent to hospital Friday afternoon with life threatening injuries after police discovered a stab wound during her arrest.

Just after 1 p.m., two Halifax Regional Police officers responded to a call of a woman behaving erratically in an apartment on Evans Avenue in Fairview.

After arriving, police thought that the woman was suffering from mental illness and presented a potential threat to her own safety and the safety of others.

She struggled as police attempted to arrest her under the Involuntary Psychiatric Treatment Act.

That was when the officers noticed that the woman had a stab wound in her torso.

Emergency responders were called and brought the woman to hospital with what were believed at the time to be life threatening injuries.

The provincial Serious Incident Response Team (SIRT) has been notified and will investigate the incident.
