A retired police officer is escorted by a police officer in Granada as he rolls his wheelchair towards the country's capital Bogota September 18, 2008. Fifteen police officers, who lost their limbs fighting against leftist rebels, and four civilians travelled 464 km (288 miles) from Cali to Bogota in their wheelchairs to demand the release of Colombian hostages held by the Revolutionary Armed Forces of Colombia (FARC).
