AOA! Bro FIA has no comparison with Police .... FIA is the Superior Investigation agency of Pakistan .... You can compare it with ISI not with police. Search for "Pakistan Intelligence Community" on wikipedia and then you will have an Idea that what is FIA ... During investigation the IO of FIA can arrest CSPs/ PSPs/Ministers and many more powerful Position Holders (If Required) But police even cannot think about it ... INTERPOL is attached with FIA in Pakistan .. FIA has collaborations with many International Investigation agencies (Scotland Yard , FBI , NIA , ) etc ... FIA is Police cum Investigation cum Intelligence Agency ...... Yes ! this agency is tried to be kept Weeker by Politicians and Corrupt elements But Still FIA is a Crownless King.....
