The Ontario Provincial Police say they will not be laying charges against Ottawa police in connection with an incident in a cellblock in September 2008.

It is the sixth incident OPP were asked to investigate involving the handling of people in the cellblock. In all cases, the OPP found no evidence of criminal wrongdoing.

"The OPP investigated the actions of Ottawa Police Service members involved in the arrest and detention of a female person in September 2008. The investigation is complete and no criminal charges will be laid by the OPP," the OPP said in a statement.

The investigation was prompted following the public outcry following the release of public video of the detention of Ottawa woman Stacy Bonds, who was kneed several times, forced to the ground and pinned by four officers before having her bra and shirt cut off with scissors.

Bonds, who is suing the Ottawa Police Service for $1.2 million, was arrested in September 2008. She was detained for alleged public intoxication, but the charge was later dismissed.

Ontario's Special Investigations Unit charged Ottawa police officer Sgt. Steven Desjourdy with sexual assault in connection with the arrest and incarceration of Bonds.

Another woman, Roxanne Carr, also launched a $975,000 lawsuit against the Ottawa police, alleging she was beaten up and stripped by officers during an August 2008 arrest.

Charges against Carr of assault, mischief, resisting arrest and assaulting police were also dropped upon review of her treatment on video.

Last November, a publicly released surveillance video also showed Terry Delay, a homeless man, being dragged to a cell by several officers and also apparently kicked by a special constable.
