Mattew Seifa has replaced Lawal Musa Daura as the new Director-General of the Department of State Services (DSS).
Shortly after the new appointment, the Acting President, Professor Yemi Osinbajo, held a meeting with the Economic and Financial Crimes Commission (EFCC) boss, Ibrahim Magu, and the new acting DSS DG.
Osinbajo had directed the termination of Daura's appointment hours after officials of the DSS stormed the National Assembly on Tuesday.
They barricaded the entrance, preventing lawmakers from getting in.
Journalists were also barred from entering the complex with the DSS officials claiming that the blockage was an order "from above."
