"Pakistan expects to receive a copy of the statement of (Jundal). I expect to have original passport claimed to have been allegedly given by (Pakistan)," Malik wrote in a message posted on Twitter late last night.
Indian authorities have said that Ansari alias Abu Jundal, an Indian citizen, had travelled to Saudi Arabia on a Pakistani passport.
In recent interactions with the media, Malik has questioned whether the passport used by Ansari was genuine. In another message posted on Twitter, Malik noted that "India had claimed earlier that (Jundal) had a Pakistani passport".
He said criminals using "fake" passports "cannot be Pakistani". In yet another message, Malik said, Pakistan "will continue to fully cooperate (with) India in the investigation of (Mumbai) terrorist attack. Pak and India need to identify their real enemy."
The two countries "need to know their real common enemy", he said.
He also raised questions about Pakistan-American terror suspect David Headley, asking "who funded him to produce movies of locations" in Mumbai.
On Wednesday, Malik had launched a stunning tirade against India's investigation of recent terror attacks. He had dismissed assertions by Indian Home Minister P Chidambaram that Pakistani state and non-state actors were involved in the Mumbai attacks and stoutly defended the ISI as an "elite agency".
He said, "We are proud of our ISI, which is defending Pakistan."
