Images of twenty-eight police officers and one soldier held hostage in southwestern Colombia being released. Around noon on Saturday, residents of the community of La Hacienda in the department of Cauca told the detainees that they were free to go. The men, held since Thursday, collected their riot gear and left along a dirt road, escorted by local residents, an AFP witness said. The government said Friday that the officers were being held by a dissident FARC guerrilla group. IMAGES
