The London Police Service will be re-opening some sexual assault cases as far back as 2010.

This comes as the police chief announced Saturday that it would doing a review of the way sexual assaults are investigated by the force.

Over a five-year period, a national newspaper report says London authorities have designated one in three of its sexual assault cases as unfounded.

Police Chief John Pare isn’t sure if this number is accurate.

“Not until we do our reviews,” he said.

But he says some cases will be re-opened.

"What we're going to do as part of our review is to look at how we're categorizing and coding and ensure that what we're doing is consistent and compliant."

Megan Walker, executive director of the London Abused Women’s Centre says while the findings don't surprise her, she considers this a systemic problem, not just a police one. She hopes all levels are held accountable, including the court system.

"Even if we solve all the issues at the police department, whatever door that woman walks through, for service, she should have the same level of support and that's not going to happen unless we take a look at the systemic issues."

Pare said the review will be done in partnership and in consultation with a number of community partners.

The review will also examine the training that investigators receive, how police can continue to enhance training, as well as explore ways in which the police may better respond to the needs of victims. 

 “The London Police Service is committed to providing the best service possible in response to victims of crime and this review will assist us in maintaining the confidence and trust of the community,” Pare said.

“Through this review we want to look at our current practices and develop best practices. What are we doing well?  What can we improve upon? And what path can we chart for the future?”
