He said, “We are working on the process of Diezani’s extradition. But we have to allow them (the UK government) because we are collaborating. There is the National Crime Agency and the Crown Prosecution Service in London, and our colleagues, the Department of Justice and the Federal Bureau of Investigation in America. We had cause to meet in London. I was there myself for about a week. We are working not only on the Diezani case; but the Diezani case has become a test case.

“It is even more notorious than the so-called Abacha loot because we have not seen anything yet. I’m sure what we have seen is not more than may be 15 per cent. I think it is going to be a long time. That is why sometimes I think we should appeal to the looters to return the loot. Come and tell the government, ‘This is what I have stolen.’ Since you have voluntarily complied with the instruction to bring back the loot, then the government will take a decision. I think it is the best way to go about it, otherwise, the monies would be wasted.

“Diezani has a lot of people who are well connected, like (Jide) Omokore who are international businessmen. They have private aircraft and you can’t see any of them in Nigeria. They went and kept them in Ghana, some of them. But we are working with almost all law enforcement agencies in the world. They are all willing to work with us because what I told them is, ‘As long as you have any (claim) of criminality in Nigeria, call us.’

Magu also noted that the anti-corruption agency is currently working on having an upgrade of its facilities as well as giving attention to the welfare of its workers to avoid undue influence or temptation in the course of their assignments.
