An independent ballistics study commissioned by AngloGold Ashanti found that his [Awudu Mohammed's] injuries could not have been caused by small arms fire as alleged and that police and mine security accounts that he was injured when he fell on the spike of a security gate are credible. Neither the official surgeons' nor the ballistic report were referred to in the "File on Four" programme, though we supplied the BBC with copies of both. AngloGold Ashanti is committed to ensuring that where its interests need to be secured, this is done in a manner consistent with international norms on human rights, including the Voluntary Principles on Security and Human Rights, to which we are in the process of becoming signatories.
