Godwin Emefiele, Nigeria’s former Central Bank Governor, pleaded not guilty to 26 new charges filed against him by the country’s financial watchdog.
The Economic and Financial Crimes Commission (EFCC) accused Mr. Emefiele of violating exchange rate regulations during his tenure as the head of the central bank.
He stands accused of improperly allocating $2 billion (£1.5 billion) in foreign exchange without adhering to proper procedures.
On Monday, the court in Lagos directed that Mr. Emefiele be held in the custody of the watchdog until the case resumes on Thursday.
Mr. Emefiele is already facing trial on 20 separate charges in a court in the capital Abuja, which include allegations of unlawfully withdrawing $6.2 million from the Central Bank.
He is the most prominent former official to face corruption charges since President Bola Tinubu assumed office last May.
His suspension came shortly after Mr. Tinubu criticized a major policy led by Mr. Emefiele during his presidential inauguration address in May, which involved the redesign of the currency, the naira.
