Ahmadu Gaada, who served as chief security officer to President Muhammadu Buhari while the latter was military head of state in the 1980s, has died.
The president sent his condolences in a message on Wednesday by his spokesman Garba Shehu.
Mr Buhari said he was saddened to hear of the demise of the “very diligent and agile security officer” who served him with excellence and astuteness.
“He worked in the national interest rather than self-interest. He will be remembered as an exemplary security officer and most of all, a patriotic citizen who placed the nation above self.
“Ahmadu’s death is a personal and irreplaceable loss to me. May Allah rest his soul in peace and give enough strength to the bereaved family members,” said Buhari.
