A Clarence-Rockland woman received a moderate injury in an Ontario Provincial Police cellblock Thursday, and the province's Special Investigations Unit is looking into it.

Just before 4 p.m. Thursday, OPP officers from the Russell County detachment responded to a disturbance on Laurier Street in Clarence-Rockland, according to a media release.

A 29-year-old woman was arrested and taken to the Russell County detachment cellblock.

"Once in the cells, the suspect caused officers to enter the cell to ensure the cell camera was in working order," the release said. "During one of the entries, the suspect received a moderate injury."

OPP would not say how the injury was inflicted, where the woman was injured, or what condition she was in.

She was taken to Montfort Hospital for treatment, and was later released back into police custody.

The woman was scheduled to appear in court in L'Orignal Friday. She is charged with breaking and entering, mischief, obstructing police and uttering threats, as well as four counts of breaching release conditions.
