Aisha Buhari, wife of the president, has denied the reports that she ordered the arrest of her aide-de-camp, CSP Sani Baban-Inna.
The ADC had been arrested and subsequently detained over allegations of fraud amounting to N2.5 billion.
A statement by Suleiman Haruna, Director of Information to Wife of the President, issued on Tuesday, however, debunked the claim that Aisha Buhari had a hand in the arrest of the ADC.
While acknowledging that the ADC did indeed use his position to defraud people, she insisted that his employers, the Nigeria Police Force, arrested him "to investigate allegations levelled against him".
The statement read: "The attention of wife of the President, Dr. Mrs. Aisha Muhammadu Buhari has been drawn to some media publications and releases purporting illegal detention of her Aide De Camp (ADC) over allegations of fraud.
"The story, as it pertains to her ADC, Chief Superintendent of Police (CSP) Sani Baban-Inna, has it that he has been detained on the orders of Her Excellency for dropping her name and defrauding unsuspecting officials and associates. She wishes to use this opportunity to refute such allegation and to state that she has no hand in his arrest and detention.
"CSP Sani Baban-Inna has been her ADC since 2016 and has been associated with her ever since. To the utter dismay of Her Excellency, he has used the opportunity to defraud unsuspecting associates and officials as initial investigations have shown.
"The Nigeria Police Force, his employers, arrested him to investigate the allegations levelled against him, this, being within their jurisdiction.
"She therefore wishes to use this opportunity to inform the general public that she has never sent any of her staff to collect any favours on her behalf or on behalf of her children and will never do so. She is therefore imploring anyone that has been defrauded by Mr. Baban-Inna to get across to him to retrieve whatever he took from them. Mrs. Buhari wishes to reiterate that she will not condone fraudulent behaviour by any of her staff.
"She uses this opportunity to call on all those in positions of authority to rise above intimidation by their aides and deal with such attitudes as extortion by name-dropping, especially within the Presidency. As she always emphasises, this government was voted into office based on the trust and confidence of the people."
