Investigations revealed that the UK Police picked up Alison-Madueke on Friday in connection with offences bordering on fraud and bribery.
The Spokesman for the UK High Commission in Abuja, Joe Abuku, confirmed to Punch that five persons were arrested by the agency.
He, however, did not disclose their identities.
It was gathered that the Seizure Organised Crime Agency within the National Crimes Agency of the UK arrested Deziani and are probing the allegations against her.
It was further learnt that Diezani was picked up by operatives of the SOCA at the instance of the Economic and Financial Crimes Commission which has been discretely probing her.
The SOCA has a working agreement with the EFCC in the area of investigation of allegations of financial crimes and proceeds of such crimes.
A source said, “It is true that the former Minister of Petroleum Resources, Mrs. Deziani has been arrested by the UK’s National Crimes Agency, not the Metropolitan Police.
“There is an agency within the National Crimes Agency called the Seizures Organised Crimes Agency. She was actually arrested by operatives of SOCA because the agency has a working agreement with the EFCC. We have been cooperating with SOCA on a number issues.
