I'll have to ask their families before sharing reports etc. Their names are Asif, Nadeem and Sarmad. They (including 2 more, who were later released after 1 month, after they paid huge amounts in rishwat) were picked up by agencies (CTD) (in front of witnesses) on 27th August 2014. Produced in court after 3 months. (Their families filed petitions in court on Thursday, 28th August).
The person who picked them was ASP Nasir Urooj (brother in law of SSP Umer Khattab). He was also fired from Anti Car Lifting Cell for corruption. He is currently wanted by Rangers for illegal kidnappings (along with 15-16 others).
