All allegations of mistreatment of Afghan prisoners by Canadian troops investigated so far have been unfounded, the Canadian Forces Military Police said Monday night.

In a release, the military police said troops "acted appropriately when interacting with the detainees."

The military police said it received about a dozen allegations of mistreatment of Afghan detainees in Canadian custody in 2006, 2007, 2008 and 2009, which were turned over to its investigative arm, the Canadian Forces National Investigation Service.

"Examples of the allegations received include complaints from detainees of having been forced to adopt a new religion, of not having been afforded the time to go to the washroom or the ability to perform ablutions for religious rituals," the statement said.

It said investigations into three allegations in 2006 and 2007 determined that they were unfounded.

There were six allegations of detainee mistreatment in 2008. In five of the cases, it was determined they were unfounded and one investigation is still underway.

"With respect to the ongoing investigation, [Canadian Forces] members have been cleared regarding mistreatment of detainees; however the investigation is still examining other remaining allegations," it said.

So far in 2009, investigations into three allegations of detainee mistreatment have determined they were all unfounded.

The statement by the military police comes as a committee of MPs looks into allegations that the Conservative government ignored warnings of abuse of detainees by Afghan authorities after they were handed over by Canadian troops.
