Abubakar gave the assurance in a statement issued by his Media Aide, Mr Paul Ibe on Saturday in Abuja.
Abubakar said that the assurance came against the backdrop of the invasion and arrest of Alhaji Babalele Abdullahi, the Finance Director of his group of companies in Abuja on Saturday.
The former Vice-President alleged that in a desperate move to make him concede and congratulate President Muhammadu Buhari, the officials of the Economic and Financial Crimes Commission (EFCC) at about 8.30 a.m. on Saturday invaded the Maitama residence of Babalele.
He said that the personnel of the anti graft agency were, however, not given access into the house until his lawyers arrived.
The EFCC agents numbering about two dozens came in two regular vehicles, an 18-seater Toyota bus (registration Abuja CS 522 RSH) and a Hilux van.
They came with a search warrant to search the house and office of Babalele and found nothing incriminating.
They then proceeded to his office at Oakland Centre in Maitama and found nothing incriminating there.
However, they took away some documents of landed properties. Not done, the EFCC officials stormed his Wuse residence where they again found nothing incriminating after the search.
Afterwards, Babalele was taken away to the EFCC office in Wuse to make a statement alongside Mr. Lawan Ayuba.
It was gathered that the petition relied upon to invade the residence and office of Babalele was authored by a brother of the wife of President Buhari.
