The money was allegedly stolen through undeclared crude oil and liquefied natural gas export.
He alleged that CBN provided conflicting responses to its inquiry on the matter and as such the governor must appear in person to clarify issues and provide necessary details needed to facilitate the probe.
“We have sent two different letters to the CBN and the bank has provided two conflicting responses to our inquiry.
“In response to the first letter, the apex bank pleaded for time due to the volume of documents required but in response to the second letter, CBN indicated that it has no record of undeclared crude,” Namdas said.
“We expected him to be here and he is not, we are disappointed.
“We will not allow any agency of government to delay the committee’s work.
“If in the next one week, the CBN Governor did not appear before this committee, we will not hesitate to exercise our powers in line with section 88 and 89 of the 1999 constitution.
