Sen. Omisore who was the Peoples Democratic Party (PDP) candidate in the last governorship election in Osun State had earlier been declared wanted by the anti-crime agency who alleged that he was evading arrest.
Omisore had also approach the court to claim damage against EFCC accusing the agency of maligning his image.
Spokesman of EFCC, Wilson Uwujaren, confirmed this on Sunday.
Although, he could not give details, Uwujaren said Omisore, a former senator, was arrested in connection with funds allegedly misappropriated by the office of the National Security Adviser (NSA) during the previous administration.
The anti-graft agency had declared Omisore wanted for allegedly evading arrest, but he denied it.
Omisore had threatened to sue the commission for defamation, and he procured a court injunction stopping the EFCC from arresting him.
He even confronted the commission on a live television programme, saying by declaring him wanted, the anti-graft agency committed the “gravest offence in the world”.
He denied receiving funds from Sambo Dasuki, former National Security Adviser.
“There was no time that I refused to honour EFCC. The point is that a company that I guaranteed worked for the office of the former NSA (Sambo Dasuki), were paid, they even sued NSA for part of their payment, so I don’t have anything to do with that,” he had said.
“I just saw on their website that they had declared me wanted and I was surprised and highly embarrassed. I am not aware of what they are talking about. I didn’t take a kobo from NSA.
“They did not even invite me. The offence EFCC committed is the gravest in the world. I am going sue them for libel.”
