Efforts to try Dick Cheney in Nigeria

Many western multinational companies have been indicted for paying bribes to Nigerian government officials to secure contracts running into billions of dollars. One of the high profile cases involved former US vice president, Dick Cheney. He was head of the American oilfield services company, Halliburton when its engineering subsidiary, KBR, allegedly paid bribes totaling 180 million dollars to secure contracts worth six billion dollars. Nigerian authorities dropped corruption charges against him after Halliburton agreed to pay a 250 million dollar fine. But anti-corruption campaigners say the settlement is illegal. One of them has gone to court in an effort to make the former US vice president face trial. Sam Olukoya reports from Lagos.
