Kabul: A gruesome video showing Afghan policemen torturing a detainee by dragging him behind a truck has gone viral on the social media.
The ensuing outrage has prompted the country's chief executive to vow the perpetrators would be punished, the Washington Post reported.
However, it is unclear whether the victim, suspected to be a suicide bomber, survived the abuse.
The amateur footage was reportedly taken in Panjwai district of southern Kandahar province.
The clip shows Afghan police tying another man to the back of a truck and dragging him across the pavement.
The video ends with the police hustling the prisoner into the cab of the truck, marked "police", the report added.
In a statement on Wednesday, the Interior Ministry said the Kandahar police force has been ordered to investigate.
Afghan security forces have "clear orders on how to behave with prisoners," the Post quoted Afghan Chief Executive Abdullah Abdullah as saying.
