Former President Muhammadu Buhari's former personal assistant, Tunde Sabiu Yusuf and billionaire businessman and oil mogul, Alhaji Auwalu Abdullahi Rano, never at any time has a dealing involving $400m, investigation reveals.

The investigation further revealed that the two person at no time fought over the said amount of money.

Investigations further revealed that reports that Sabiu slapped AA Rano for allegedly failing to account for a purported $400million he gave the billionaire businessman for safe keeping were not true.

An online media report recently claimed that both Sabiu and AA Rano had a fight over the inability of the billionaire to properly account for the $400m he gave him for keep.

The report also alleged that Rano had allegedly been helping Sabiu to launder stolen funds by investing in properties, maritime, oil and air transport businesses.

The two men, according to the report, however, fell out following disagreements that arose over the mismanagement of the funds allegedly by AA Rano.

Our investigation further revealed that such an incident between Buhari's ex-aide and AA Rano never occurred at any point in time, anywhere, as there has never been any business relationship between both men to warrant any exchange of funds.

It was also discovered in the course of our investigations that President Bola Tinubu's Special Investigator for the Central Bank of Nigeria, Jim Obazee, who was said to have been investigating Sabiu, has not found any trace of AA Rano's involvement in the allegation against Sabiu.

Meanwhile, investigation by our correspondent further revealed that none of the individuals close to Sabiu or alleged to be part of the investigation was from the North.

 "We've not found out that Sabiu gave any $400m to AA Rano and both of them never fought over such money," a security source told our correspondent.

Efforts by our correspondent to speak with both Sabiu and AA Rano on the matter proved abortive as none of them could be reached as of press time.

But a chieftain of the umbrella Northern socio-political group, Arewa Consultative Forum (ACF), who pleaded not to be identified, described the media report accusing AA Rano of collecting $400million from Sabiu as "wicked, malicious, in bad taste and aimed at maligning a gentleman businessman.

“AA Rano that we know has never had any business relationship with Tunde Sabiu. None at all! And he'll never get involved in such illegal and unpatriotic act. So, that $400million deal is just a figment of the imagination of the writer of that story."
