Former Winnipeg police officer Richard Dow has pleaded guilty to some of the 27 sexual assault and other charges he faced in relation to the modelling agency he ran as a side business.

Dow, 57, pleaded guilty on Tuesday to 11 counts of sexual assault and one count of simple assault. Thirteen other charges against him were stayed.

Last week, a jury found Dow not guilty of sexually assaulting a female modelling client during a photo shoot at his home in 2000.

Dow, who operated the Ricoco International modelling agency as a side business, insisted during the trial that he had consensual sex with the woman, who was 18 years old at the time.

Dow was set to go on trial this week on 27 additional charges. The Crown alleged that he sexually assaulted or sexually interfered with 20 different women between 2000 and 2005.

The latest trial began on Monday, but legal wrangling delayed the start of proceedings until late Tuesday afternoon, when Dow entered the guilty pleas.

Crown prosecutors then described each of the 11 sexual assault cases, almost all of which happened at photo shoots.

The victims were between the ages of 17 and 23 at the time of the assaults, which involved inappropriate and unwanted sexual touching, the court heard.

In one case, Dow told the mother of one young woman that he could be trusted because he was a police officer, court was told.

Dow is scheduled to be sentenced on Aug. 24. The Crown is calling for a prison term, while the defence wants a conditional sentence.

Dow retired from the Winnipeg Police Service in 2007, after an 18-year career.
