An Ottawa police internal disciplinary hearing into the conduct of Sgt. Steven Desjourdy during a controversial cellblock incident in 2008 wrapped up Wednesday and final arguments are expected Thursday.

The hearing will determine whether Desjourdy is guilty of discreditable conduct under the Police Services Act for leaving a woman topless in her cell for several hours.  The woman cannot be identified because of a publication ban.

After testifying Tuesday, Desjourdy was cross-examined Wednesday by prosecutor Robert Houston, who pointed out an inconsistency between Desjourdy's testimony on Tuesday and what he had said under oath three years ago during at the woman's preliminary hearing.

During that hearing, Desjourdy testified that he left the woman alone in a cell topless for so long because he had other duties to attend to.

At the time the woman was half naked; her shirt and bra had been cut off during a strip search after she mule kicked an officer in the cellblock area. Desjourdy faced a criminal charge of sexual assault, but was acquitted last year.

Sgt. Steven Desjourdy was acquitted of a criminal charge of sexual assault in 2013.

It took more than three hours for Desjourdy to provide her with temporary clothing called a blue suit.

On Tuesday, Desjourdy said he did not give her the blue suit earlier for safety reasons, because he was worried she might be suicidal and could use the blue suit to strangle herself.

He said she was behaving bizarrely in her cell, trying to push herself through the bars to get out, and that he said he had never seen anything like that before.

On Wednesday Houston asked why, if her behaviour was so unusual, Desjourdy didn't mention it during the woman's preliminary hearing.

Desjourdy said he wasn't asked directly about it. He said that hearing focused more on the events surrounding the cutting of her bra, not on what happened while she was in the cell.

The woman is not testifying at Desjourdy's disciplinary hearing.

Final submissions will be made Thursday. If found guilty of discreditable conduct, Desjourdy could face a demotion to constable.
