A new report obtained by CTV News says that Canadian military police failed to properly investigate the injuries of three Afghan militants who were captured by the Canadian Forces.

An inquiry was launched after University of Ottawa law professor Amir Attaran formally complained that the three detainees may have been mistreated by their Canadian capturers.

The independent military police complaints commission report says that the detainees were transferred over to Afghan authorities before Canadian military police finished their questioning.

"They violated their orders, they didn't investigate," Attaran said of the military police.

But the report concludes that there was "no attempt . . . to cover up their possible mistreatment" on the part of the Canadian Forces. It also said the detainees were offered good medical care and were treated humanely by military police.

Foreign Minister Lawrence Cannon said the government is "very pleased with that finding."

However, the report says there was a "surprising lack of awareness" by military police about their duty to investigate the injuries of detainees.

Also, there was a "general and pervasive pressure from the chain of command for maximum haste" in transferring prisoners from Canada's control into the hand of Afghan authorities.

The military has claimed that one of the detainees was injured by resisting capture and the other two were injured while trying to escape.

"We don't know it was abuse or not in this case and we will never know, and that's because the procedures to investigate were not followed," Attaran said.

Defence Minister Peter MacKay will not comment until the report is officialy published, a spokesperson told CTV News.

According to the Canadian Forces' website, the three Afghan were captured on April 6-7, 2006. The trio were then transferred to the Afghan National Police on April 8.

Attaran formally complained to the Military Police Complaints Commission on Jan. 29, 2007.
