Mr Obiora has now spent four nights in custody under questioning by the security service, which has been looking into allegations of financial mismanagement under Godwin Emefiele, the ousted governor.
Mr Emefiele, who was first appointed as CBN governor in June 2014, has been in SSS since June 10, 2023, a day after he was controversially removed from office by President Bola Tinubu.
While two federal judges have ordered Mr Emefiele’s release, the SSS has continued to find other grounds to hold him in custody, often filing fresh charges to supersede earlier ones for which the top banker had been arraigned.
