According to a spokesperson for the commission, Wilson Uwajaren, the former NDDC MD allegedly diverted the funds.
The 56-year-old was the All Progressives Congress (APC) governorship candidate for Akwa Ibom in the 2019 elections. He also lost the People’s Democratic Party (PDP) gubernatorial primary election to Governor Emmanuel Udom in 2015.
Nsima was the NDDC’s Managing Director between 2016 and 2018.
His arrest is the latest scandal to have been linked to the NDDC after President Muhammadu Buhari ordered a forensic audit of the agency in 2019.
The audit, which is being reviewed, covered the operations of the organisation from 2001 to 2019.
President Buhari, who lamented the alleged financial misappropriation in the NDDC, said his government will recover “every kobo” misappropriated.
