The cases against Zardari are part of the investigations being conducted by NAB in pursuance of the Supreme Court's verdict in the money laundering of billions through fake accounts case.
On Monday, former president and Pakistan People's Party (PPP) co-chairman Asif Ali Zardari surrendered himself to a team of the NAB after the Islamabad High Court (IHC) rejected his and his sibling Faryal Talpur's pre-arrest bail plea in the money laundering case.
Zardari, the husband of assassinated ex-Prime Minister Benazir Bhutto, served as president from 2008 until 2013.
The two attended the court hearing but were not arrested at the scene. He denies wrongdoing in this latest "fake accounts" case.
Pakistani authorities previous year discovered several accounts, registered in the names of poor people, that had been flooded with cash, then suddenly emptied.
Zardari has repeatedly dismissed allegations he had a hand in the scheme, calling the government an instrument of the powerful military and labelling the prime minister, Imran Khan, the army's "blue-eyed boy".
"He earned himself the nickname of Mr Ten Percent because of all the money he was taking on the deals", he said.
It is pertinent to note that the National Accountability Bureau (NAB) has already issued arrest warrants for the former president in the case.
Mr Zardari and his sister allegedly made transactions of Rs 150 million through alleged fake bank accounts, officials told PTI.
BBC correspondent Secunder Kermani says Mr Zardari has always been considered one of the most controversial figures in Pakistani politics.
The anti-graft body has arrested several politicians and businessmen on corruption charges since Khan took office past year after winning a narrow majority in parliamentary elections.
