The Special Investigations Unit has been called in to examine the death of a 38-year-old Ottawa man in North Bay.
The SIU takes over cases in which someone has been killed or seriously hurt after police intervention.
North Bay Police were called to an apartment building in the city for assistance at about 1:30 Sunday afternoon.
The SIU says the man was found near the building, and fell from it to the ground below at 2:30.
There is no information on what happened in between the arrival of the officers and the man's death.
An autopsy has been scheduled for Tuesday.
