The Economic and Financial Crimes Commission (EFCC) is currently probing 52 companies over forex transactions.
The commission is investigating forex allocations to these companies during the tenure of Godwin Emefiele as governor of the Central Bank of Nigeria (CBN).
The EFCC wrote to the various companies asking for documentation on their forex transactions in the last 10 years.
Some of the big companies being investigated are Dangote Group, BUA Group and Flour Mills — but they have all denied wrongdoing in their communications with the EFCC.
