Sani Baba-Inna, aide-de-camp of the wife of the president, Aisha Buhari, is presently in the custody of the Department of State Services (DSS).
He is being detained following allegations of N2.5 billion fraud.
Peter Afunnaya, spokesperson of the DSS, confirmed the development, according to The Nation.
Aisha Buhari is said to have alleged that the ADC had received huge donations from politicians and business people, yet kept the money to himself.
The Inspector General of Police has also been asked to arrest and subsequently detain Baba-Inna, and force him to refund the said amount.
According to the DSS, investigation is ongoing.
