The UK National Crime Agency [NCA] on Saturday said investigation into allegations of corruption against Nigeria’s former minister of Petroleum Resources, Diezani Alison-Madueke, and the four other people arrested Friday had been on since 2013.
In an update on its website, the NCA said, “The investigation commenced in 2013 under the Proceeds of Corruption Unit, and transferred to the NCA earlier this year.”
Until recently, the Proceeds of Corruption Unit was domiciled at the Metropolitan Police Service.
But after the International Corruption Unit was created at the NCA in line with the UK Anti-Corruption Plan, the Proceeds of Corruption Unit at the Metropolitan Police and the Overseas Anti-Corruption Unit of the City of London Police were scrapped.
The ICU then became the UK’s prime agency for the investigation of bribery of foreign public officials by individuals or companies from the UK, and money laundering by corrupt foreign officials and their associates.
In its update Saturday, the NCA also said it had released the former minister on “conditional bail”.
The other four unnamed persons arrested with her were also granted bail.
“All five people arrested were released on conditional police bail later that evening, pending further investigation both in the UK and overseas.”
The conditions of the bail are not immediately clear.
But people familiar with the matter revealed that Mrs. Alison-Madueke and her colleagues were barred from travelling out of the UK pending conclusion of investigation and their arraignment in court.
One Source revealed that the suspects’ travelling documents were seized.
The source also said the suspects were also warned against any attempt to tamper with evidence.
