Using martial arts?

Using martial arts? Are you sure we're not talking "plain old" torture here? In any case, this sounds really bad.

Story:
Vietnam -- "The Security police was using forms of martial arts such as Karate and Kung Fu. It seemed as if he was practicing his strikes on a restrained Yum. As blood flowed down from Yum’s mouth, nose and ears, Yum fell down on the floor unconscious. At noon they let Yum go back home, but by the time he arrived, his face, eyes and lips were all bruised and swollen and he couldn't eat. As of now, he is still suffering from those severely beatings," the group added.

Grun, who is from the same village, was named as another victim. He was also taken to the local Security Police station on January 24 where officers allegedly "were using martial arts to beat him mercilessly." Although Grun "did not talk back to them, they still beat him up severely." At noon Grun too was allowed to leave "but his face and eyes were all bruised up and swollen and he could barely walk," MFI claimed. He is reportedly unable to work and is recovering from what MFI described as "severe" injuries at home.
