Ibrahim Magu, the acting chairman of the Economic and Financial Crimes Commission (EFCC) has been suspended by President Muhammadu Buhari.
A presidential panel headed by Justice Ayo Salami had earlier been set up by Buhari to probe the various allegations leveled against the EFCC boss.
The panel grilled Magu for hours on Monday at the Presidential Villa, Abuja, before he was taken into police custody.
Magu was said to have spent the night in a police cell following his invitation to the State House to appear before a panel investigating allegations of corruption against him.
The Presidency has yet to issue a formal statement on the issue as of the time of filing this report.
The presidential panel has, however, resumed sitting at the Presidential Villa, Abuja over this case.
