The UK’s National Crime Agency (NCA) has frozen London properties valued at £10 million allegedly bought for the former Minister of Petroleum Resources, Mrs. Diezani Alison-Madueke, as investigations into the case against her unravel by the day.

The two properties located at Regents Park in London, along with one in Buckinghamshire, have now been frozen based on the request of Nigerian authorities.

According to online news medium, a London court gave the freeze order in September 2016 but details of the rulings have only recently become public.

But the agency was too late in preventing a further two properties worth £8 million from being sold.

In July, the U.S. Department of Justice (DoJ) had revealed four properties it alleged were bought for the former petroleum minister by individuals and firms seeking her influence in obtaining lucrative oil assets and crude oil lifting contracts.

Some of the oil assets were assigned to people believed to be her cronies through Strategic Alliance Agreements (SAAs).

The DoJ’s affidavit stated that businessmen, Jide Omokore and Kola Aluko were involved in the purchase of two of the properties allegedly bought for Alison-Madueke.

The UK order obtained by Africa Confidential, a newsletter specialising in politics and business in Africa, has revealed that three of the properties have been frozen under the Proceeds of Crime Act.

Apart from Alison-Madueke, Omokore and Aluko, the order also named three other individuals as defendants in the case, all of whom were believed to have received contracts or oil assets from the NNPC during the embattled minister’s tenure.

The order forbids the defendants from disposing of or dealing in the properties.

Although the NCA has frozen three properties valued at £10 million, the agency was too late to prevent a further two properties worth £8 million from being sold.

One of these, a massive nine-bedroom house in London’s exclusive Hampstead Garden Suburb, bought by a British Virgin Islands-registered company in January 2011 for £5,850,000, was sold in May 2015.
