The secret police said Sani Baba-Inna, a chief superintendent of police, is being interrogated.
PREMIUM TIMES had reported how Mrs Buhari petitioned the police alleging her ADC defrauded her of N2.5 billion.
On the heels of that, the Police, arrested Mr Baba-Inna and raided his home in the Garki District ofon Friday.
However, checks on his bank account showed that he did not carry money of such magnitude in any of those locations.
Not satisfied, Mrs Buhari asked the SSS to take over the investigation.
The spokesperson of the service, Peter Afunanya, had told PREMIUM TIMES that he was not aware of the arrest but would revert once he received information on the matter.
Mr Afunanya kept his word and called the newspaper this afternoon to confirm that Mr Baba-Inna was in custody at the headquarters of his agency in Abuja.
“He was handed over by the Police and investigation is ongoing,” he said.
A member of the Baba-Inna family also informed us that the SSS allowed Hassana, the wife of the ADC to meet him today.
