The province’s Special Investigations Unit has been called in after a 30-year-old man died following an interaction with police early Wednesday morning in Mississauga.

Peel police were called to Runningbrooke Drive and Riverspray Crescent, near Tomken Road and Burnhamthorpe Road East, for reports of a disturbance just after 3:15 a.m.

The SIU says when police arrived, they located a person of interest in the backyard of a home. A struggle ensued in which “several use of force options” were used including a Taser to take the man into custody.

Soon after the man lost all vital signs and was rushed to a hospital where he was eventually pronounced dead just after 4 a.m.

The SIU would not say how many officers were involved in the struggle with the victim or how many Tasers may have been used but it has identified three officers who were involved in the incident and two others who witnessed it.

“I know that a weapon was deployed and whether he was struck by it and whether it had any effect on him, that will be part of our investigation,” said SIU spokesperson Monica Hudon.

No officers were injured as a result of the struggle with the man, according to the SIU.

This is the second stun-gun death in Mississauga in recent months.

The SIU is also investigating the death of a 34-year-old man who died after police used a stun gun on him on Sept. 10.

In that case, the watchdog said Peel police officers responded to a domestic call in the Malton area around 9 p.m.

The SIU said the “officers became involved in an interaction with a man which involved the use of a conducted energy weapon.”

The agency said the man stopped breathing, his heart stopped beating and he was later pronounced dead in hospital.
