(Ecofin Agency) - The former Minister of Petroleum Resources Mrs Diezani Alison-Madueke who was arrested last week by the United Kingdom’s National Crime Agency (NCA) will not be able to leave the United Kingdom, until April, next year when the investigations into allegations filed against her are likely to have been concluded, according to Judiciary sources.

Alison-Madueke was arrested along with four others. She was however granted bail but her international passport was seized.

Recently, the London Westminster Magistrate’s Court on Marylebone Road approved the holding of the £27,000 cash seized from her, following an application brought by the NCA under the Proceeds of Crime Act in the UK.

The court also ruled that the cash would be held for six months – till April, next year when she is expected to be arraigned after investigations.

It was also gathered that the court also granted the order that she should remain in London while investigations is still on-going.

Meanwhile, The United Kingdom has also demanded for Mutual Legal Assistance from Swiss authorities for the detention of Mr. Kola Aluko, the alleged money launderer for Alison-Madueke and former President Goodluck Jonathan.

Nathalie Guth of the Office of the Attorney General of Switzerland in an email to SaharaReporters, said, “I can give you the additional information, that the OAG has received a request for mutual assistance from England.” Revealing that it was the UK, not Nigeria, requesting Mr. Aluko’s detention contradicts reports that it was Nigeria which had requested the assistance from Switzerland.
