The Economic and Financial Crimes Commission (EFCC) has arrested former minister of state for Finance, Mrs Nenadi Usman, reports say.

Punch reports that Usman is being quizzed for allegedly receiving N2.5b from the Central Bank of Nigeria  (CBN), to fund the 2015 presidential campaign of former President Goodluck Jonathan.

A source from the EFCC reportedly said the former minister was the one who disbursed all the funds used during GEJ's campaign.

According to reports, N2.5b, out of the N4b transferred to an account called Ministry of External Affairs Library, was allegedly paid into Usman’s company account.

The former minister then disbursed the funds to different groups and individuals that were involved in the presidential campaign of former President Jonathan.

The Ministry of External Affairs Library account reports say, was created by the Office of the National Security Adviser (ONSA) to siphon funds for GEJ’s campaign.

An EFCC source who also spoke to Punch said “A lot of people who received money during the campaign claimed to have received money from Nenadi Usman. Since she was in charge of funds, she will be able to list the names of those who collected money and if the money was approved by Jonathan.

“There is no part of the constitution which gives the CBN the right to fund a political party. Usman must therefore tell us why the CBN gave her money.”

Mr. Warimopei Dudafa, a Special Assistant on Domestic Affairs in the Goodluck Jonathan administration, was also arrested by the EFCC on Monday, April 18, 2016.
