1-My father in law being government employee took subsidy for opening fish farm .During that period he was suspended from job from not present later when didn't succeeded ,re-join office on basis of medical ground ( now query) a-whether he is eligible for subsidy for extra income away from office without intimation. b-he had taken cheques during absent but shown himself medical unfit for re-joining after suspension. c-So medical certificate are fake as he was running fish farm as cheques of subsidy as RTI reply I had detail. d-Also since 2002 -2016 when he left govt accommodation not paid any electricity bills and water bills . e- I have intimated his govt employer 1 week before retirement but he did not took action . f- while filing RTI against govt Fish farm agency ,Bank who gave subsidy without checking KYC more over subsidy and loan for which he is not eligible
