From Saharareporters:

We just learnt that officials of the Economic and Financial Crimes Commission this afternoon arrested immediate past Governor of the Central bank of Nigeria, Charles Soludo in connection with the Australian polymer banknotes bribery scam.

A close relative of Mr. Soludo confirmed to Saharareporters operatives picked up the former CBN governor in Abuja a few hours ago.

 A government source told Saharareporters that Mr. Soludo is facing interrogation by the EFCC at its Abuja office with regards to his role in the bribery of CBN officials by an Australian currency mint company, Securency.

 The source told our reporters about a dozen other CBN former and serving CBN officials have also been apprehended for questioning on the deal.
EFCC spokesperson could not be reached for confirmation of the arrest.
