EFCC recovered $9.8 million in cash from a secret bunker owned by Dr. Andrew Yakubu who is a former Group Managing Director of the Nigerian National Petroleum Corporation.
According to EFCC, the discovery was made on February 3 in a building belonging to Yakubu which is located in the slums of Sabon Tasha area of Kaduna.
The anti-graft agency said the former NNPC GMD confessed that the money was his and that it was given to him by unnamed persons.
