The Special Investigations Unit is appealing for witnesses to come forward as it investigates the death of a man in Washagamis Bay, southwest of Kenora.
The provincial agency says the 29-year-old was first arrested at a home on February 27th after Provincial Police received a complaint.
He was once again arrested the following day outside the Kenora Fellowship Centre.
On both occasions the man was lodged in a cell for a few hours and then released.
Police and emergency personnel responded to a medical distress call at the man’s home on March 5th.
He died shortly after being transported to hospital.
The SIU has assigned two investigators and two forensic experts to the case.
The agency investigates reports involving police where there has been a death, serious injury or allegations of sexual assault.
