The copies of two NAB supplementary references were handed over to Nawaz Sharif.
To which, he said the IO didn't document his statement rather took signature on a memo.
The Bureau also asked the ministry to impose travel ban on Mr Sharif's daughter Maryam Nawaz and son-in-law Mohammed Safdar saying "it is possible that the accused attempt to flee the country".
Marriyum Aurangzeb also questioned that why names were being placed in the Exit Control List (ECL).
The anti-graft watchdog wrote a letter to the interior ministry, asking it to include the names of the former premier, his daughter and son-in-law on the ECL.
Interior minister Ahsan Iqbal who is visiting Norway, said that a decision would be taken after his return and it would be in accordance with the law.
The interior ministry is unlikely to heed to the NAB's request.
The former prime minister and his family members, including Hasan and Hussain Nawaz have been nominated in three references filed by the National Accountability Bureau (NAB) regarding Al-Azizia Steel Mills, Flagship Investment and Avenfield.
Earlier, it was reported, based on sources, that NAB Chairman Justice (retd) Javed Iqbal has approved the filing of references.
According to reports, eight new witnesses in each reference, as well as fresh evidence gathered against the Sharif family has been made part of the supplementary references. The Flagship Investment reference contained additional information about the ruling family's offshore companies.
He was irked when a NAB prosecutor sought more time to file the references against Sharif. However, he didn't turn up.
A five-member bench of the Supreme Court on July 28 had directed NAB to file references against Nawaz and his children in six weeks in the accountability court and directed the trial court to decide the references within six months.
Nawaz and his son are accused in all three cases, while Maryam and Safdar are named in the London properties case.
