The commission said the former governor had not been released.
Mr Wilson Uwujaren, the Head of Media and Publicity of the EFFC, on Friday told Newsmen that: “The former governor is currently in our custody undergoing interrogation and I cannot say exactly when he will be released. I don’t know how long the exercise will take.
“All I can tell you now is that he is still in the EFCC custody in Abuja,” he said.
