Ontario’s police watchdog has been called to investigate the death of a woman following a police-involved shooting in Hamilton early Saturday morning.

Witnesses who were at the scene said officers were called to 320 King Street East just before 1 a.m. for reports of a “disturbed person with a knife.”

The two-storey building, located at King Street and Wellington Street North, is e-One Vapor; an e-cigarette and e-liquid shop.

The woman was reportedly rushed to hospital without vital signs and later pronounced dead.

Hamilton police would not comment on the incident because the SIU has invoked its mandate.

The SIU is an arm’s length agency that investigates reports involving police where there has been death, serious injury or allegations of sexual assault.
