Ontario's Special Investigations Unit has discontinued an investigation into a serious injury sustained by a man inside of a Brampton courthouse cell after determining the injury was self-inflicted.

On Tuesday, April 30, the man was lodged in a cell at the A. Grenville and William Davis Courthouse and covered a surveillance camera lens with wet toilet paper before special constables came in to handcuff him, according to SIU interim director Joseph Martino.

A short time after constables left the cell, the man stood atop a privacy wall in the cell, and as the constables returned to the cell equipped with leg shackles, the man attempted to step onto a nearby bench. His right arm hit the edge of the bench when he fell and he was taken to hospital for treatment.

Martino said the man suffered a fractured right shoulder and explained it was "Manifestly clear at this time that no police officer caused or contributed to the man’s injury in any fashion that could attract criminal liability."
