dear i have the same case like you.i appeared in TAS/TA/OS by NTS under MOD in lahore.i was shortlisted for second stage.when second stage came for inspector,sub inspectors,AD etc.my name was not in the list.i enquired NTS,nts replied me that TAS/TA/OS posts have been taken back by MOD.so no more stage for TAS/TA/OS.
this is real picture of the test.
