A post-mortem was performed Monday after a 21-year-old man was shot and killed during an altercation with Timmins Police on Saturday morning.

It happened, in the area of Brunette Road and James Avenue of Timmins.

Reports say officers went to an emergency medical services building to "deal with a man." 

The Province’s Special Investigations Unit says the man fled, and when officers followed, there was an "interaction," during which one of the officers fired a gun.

Ontario’s SIU was called in to investigate after the man was pronounced dead in hospital.

As they began that case, word of a second investigation involving the police force and another death on Saturday also came out.

The SIU says the second one involved a 62-year-old woman dying while in custody of the Timmins Police Service, Saturday night.

At 2:45 p.m. on Saturday, police were called to the Timmins District Hospital to investigate a woman. When asked to leave, the woman got into a taxi and left.

A short time later, the woman was allegedly causing a disturbance at a local shelter, so officers arrested the woman and put her in a jail cell.

An ambulance was called at 10 pm and the woman was taken to the hospital.

On Sunday, police were notified that the woman had been pronounced dead in hospital. 

Two provincial investigators and a forensics specialist have been assigned to this incident.
