A/HRC/10/9 page 25 Information from sources 100. Additional information was received from sources concerning 40 outstanding cases. Clarifications The Working Group clarified four cases for which the six-month rule expired as no observations were received from the source. Prompt intervention letter 101. On 6 October 2008, the Working Group sent a prompt intervention letter to the Government of Colombia regarding acts of intimidation and reprisals suffered by the family members of a person who disappeared on 29 July 2002. According to the source, the Mayor of Agua Azul, the city where the family lived, was not only responsible for the disappearance of the victim but also for intimidating his family. 102. On 13 October 2008, the source informed that on 11 October 2008, the Mayor of Agua Azul was arrested after the Prosecutor of the Human Rights Unit issued an arrest warrant against him for the alleged crime of enforced disappearance and conspiracy to commit a criminal offence. 103. On 17 November 2008, the Working Group sent a joint communication together with the Special Rapporteur on the situation of human rights defenders and the Special Rapporteur on the promotion and protection of the right to freedom of opinion and expression, regarding the threats and acts of intimidation suffered by five human rights defenders due to their activities related to the investigation of enforced disappearances. 104. No response was received from the Government regarding the above reported prompt interventions. General allegation 105. Information was submitted by credible sources to the Working Group concerning obstacles allegedly encountered in the implementation of the Declaration. This information was transmitted to the Government through two general allegations. 106. On the first general allegation, credible sources reported that the number of people that have disappeared in Colombia in recent years may reach 30,000. In 2000, the Government investigated 3,500 disappearances. In 2007, that number rose to 15,600 investigations. 107. According to credible sources, the number of disappearances is much higher than the official figures because of a poor and inefficient administrative system in the country, especially in the rural areas of Colombia.
