SUDBURY -- The organization that investigates police in Ontario has cleared Sudbury police in a Sept. 27 incident in which a man in custody broke his hand.

While the case seemed a clear example of a suspect hurting himself, the Special Investigations Unit automatically looks into any incident in which someone is injured while dealing with police.

In this case, the man was arrested Sept. 26 on charges of assault and uttering threats. The next day, he appeared on video from the jail, where a judge ruled he would be remanded into custody.

"Shortly after, the man punched a wall inside the video conference room," the SIU said in a news release Friday. "He was taken to hospital where he was diagnosed with a broken right metacarpal."

“Based on the SIU’s preliminary inquiries, which included a review of video recordings taken of the man’s time in custody, it is evident that the man is alone to blame for his broken hand," Joseph Martino, director of the SIU, wrote in his decision.

"On this record, as there is patently nothing to further investigate regarding the potential criminal liability of any police officer in connection with the man’s fracture, the investigation is hereby discontinued and the file is closed.”
