ISLAMABAD - Directorate General Intelligence and Investigation of FBR has pressed ahead with its probe into fake issuance racket by four accused held last week. According to the details, further interrogation of two of the accused, namely Muhammad Shafqat S/o Muhammad Qasim and Mohsin Hanif S/o Muhammad Hanif, reveals that Shafqat, a computer expert, would take advantage of the FBR's website's Taxpayer Facilitation Portal and decode the user ID and password of inoperative/Nil file/closed units. The modus operandi was that once a person approached Shafqat with NTN number of a registered person, the accused Shafqat fed that in the e-enrollment field of FBR's web portal and got CNIC of the owner of that particular unit.
