According to a highly placed source in the PCB, the committee will talk to captain Shahid Afridi, head coach, Waqar Younis, manager Intikhab Alam and some players in the World T20 squad when the team returns home from India.
"The committee will also talk to the other members of the support staff including the security manager, assistant coach and batting coach Grant Flower," the source said.
The development comes just two days after PCB Chairman, Shaharyar Khan said at a press conference in Lahore that they were no groupings in the team and that the players were motivated and united.
The fact-finding committee, which includes present Test captain Misbah-ul-Haq and senior batsman Younis Khan, has already met thrice to probe into the Asia Cup debacle when Pakistan lost to India and Bangladesh.

Younis had declined to attend the meetings insisting he would make an appearance after the World T20 is over.
The source said that Shaharyar was deeply disturbed after the way Afridi and Waqar spoke after the loss to New Zealand.
"The comments made by both indicated all is not well within the team," the source added.
Waqar blasted his players without naming anyone for their inapt performances but referred particularly to Umar Akmal and Ahmed Shehzad.
Shaharyar has copped some criticism for his comments made during the World T20 when he said that the captain and coach would be changed after the event.
