Iniobong Effiong, a staff member of Diamond Bank, on Wednesday testified against Olisa Metuh, spokesman of the Peoples Democratic Party (PDP).

Effiong, who managed the account of Metuh’s Destra Investment Limited at Diamond Bank, claimed that Sambo Dasuki, former national security adviser (NSA), paid a sum of N400m into the company’s account on November 24, 2014. She claimed that prior to the deposit of the sum by the former NSA, the company’s account balance was N6, 636, 576 million.

Earlier Okon Abang, justice of the federal high court, Abuja, had delivered a bench ruling admitting some documents tendered by Tahir Sylvanus, the prosecution counsel, as evidence against Metuh. Emeka Etiaba, counsel to Metuh, had asked the court to dismiss some correspondence between Diamond Bank and the Economic and Financial Crimes Commission (EFCC) as evidence against his client.

But Abang overruled his application for lacking in merit. He therefore admitted, in evidence, a letter from Diamond Bank to the EFCC containing the statement of account, account opening document and certificate of identification of Destra Investment Limited. He also admitted, in evidence, a letter from the EFCC to Diamond Bank asking for the bank details of the company. Effiong is the fourth witness to testify against Metuh.

On Monday, Nicole Ararume, another witness, had claimed she received $2m from Metuh, which she converted into naira and transferred to the PDP spokesman’s account. On Tuesday, Bali Ndam, a legal officer at the office of the national security officer (NSA), had also claimed that the former NSA paid N400m into Metuh’s Destra Investment Limited account without an award for any contract.
