Nwachukwu, who is the second prosecution witness in the trial of Saraki at the Code of Conduct Tribunal (CCT), had on Tuesday testified that the accused person operated foreign bank accounts.

He gave this testimony while being led in evidence by Rotimi Jacobs, the prosecution counsel.

However, upon cross-examination by Paul Usoro, counsel to Saraki, the witness admitted that there was no evidence that the said accounts were the senate president's.

And on Wednesday, when Usoro asked him to explain why he could not confirm the identities of the accounts, Nwachukwu said the documents confirming the transfer of funds were destroyed in an inferno, and that he did not see them prior to that time.

Also, when asked how he got the documents he sent to the EFCC, the witness said he was not the "officer responsible for the documents that were forwarded to EFCC", and that he has "no knowledge of that ".

Shortly afterwards, the tribunal adjourned to February 8 for continuation of trial.
