Mele Kyari, former Group Chief Executive Officer of the Nigerian National Petroleum Company Limited (NNPCL), on Wednesday, appeared at the headquarters of the Economic and Financial Crimes Commission (EFCC) in Abuja around 2:15 p.m. His visit followed an invitation by the anti-graft agency to respond to questions on financial and technical issues relating to his tenure in office. It will be recalled that the EFCC had earlier placed Kyari on its watchlist as part of its ongoing investigation into the $7.2 billion refineries’ turnaround maintenance. Meanwhile, the Federal High Court in Abuja has ordered the temporary freezing of four bank accounts linked to Kyari over alleged fraud.
