In a letter dated october 11 2016 and addressed to the office of the chief justice of Nigeria (CJN), Mahmoud Mohammed, Justice Ademola explained that his arrest was in connection of his rulings for the release of Biafran Republic agitator, Nnamdi Kanu and former National Security Adviser, Sambo Dasuki. The two rulings were to be ignored by officials of the DSS who held both Kanu and Dasuki against the court rulings.
According to Justice Ademola's letter:
"…Upon signing the document, they told me that I am under arrest and ordered me with guns still pointed at me to move outside. As I was going, they told me they were taking me to their office, Department of State Services (DSS) office, without showing any warrant of arrest.
"I obeyed them and about six o’clock in the morning, I was whisked away from my residence to the DSS office without any warrant of arrest or reason for my arrest.
"From the time of my arrival at the DSS office, at about 6:45am on 8/10/2016, I was not told what my crime was for over 24 hours till the evening of 9/10/2016.
"A DSS officially finally informed me that the search of my arrest were based on these three allegations; petition of Hon. Jenkins Duvie dated 4th of April 2016 to the National Judicial Council (NJC); granting bail to Col. Sambo Dasuki and the unconditional release of Nnamdi Kanu; and using my office to secure my wife’s appointment as the head of civil service state through Senator Bola Tinubu.
"What is more intriguing in this whole episode, is that I see it as a vendetta/revenge from the Hon. attorney general of the federation, Abubakar Malami, whilst I was in Kano between 2004 and 2007 as a federal high court judge was involved in a professional misconduct necessitating his arrest and detention by my order.
"However, with the intervention of the Nigerian Bar Association (NBA), Kano branch the allegation of misconduct was later withdrawn by me."
