Ontario's police watchdog has closed an investigation into the Windsor Police Service because the complainant is not cooperating.
The Special Investigations Unit began its investigation after the arrest of a break and enter suspect on Chatham Street in late October.
There was a brief struggle before the arrest and the man complained of pain when brought to the police station.
He was taken to hospital for treatment.
The SIU was not able to reach the suspect, but family members indicated he did not want to speak with the investigators from the unit.
The investigators could not determine if there were any injuries.
As a result the SIU Director has terminated their probe.
