National detective chief Lt. Gen. Sutarman said Friday that several other officers are still being questioned in connection with the 14-minute video of the anti-terror squad, known as Detachment 88. The blurry footage from a 2007 counterterrorism operation in Poso showed officers trampling and yelling at shirtless, bound suspects lying face down on the ground.
One man wearing only his underwear is shown with a bloody hole in his back, presumably from a gunshot wound.
Sutarman, who uses only one name, said the five officers were arrested Thursday.
The video, posted recently on YouTube and Muslim websites, has sparked outrage among Islamic groups.
