The IIO is investigating after the death of a man in a Kelowna jail cell Saturday afternoon.
Mounties had taken the man into custody the night before, after a single vehicle accident where he collided with a tree.
In a release, the RCMP say he was taken to hospital that evening, but cleared to leave by hospital staff.
The next day paramedics were called after he was found unresponsive in his cell, shortly after 2 p.m.
He was pronounced dead just before 2:40 p.m.
The RCMP has also initiated an Independent Officer Review.
