The Internal Affairs Division, also known as the IAD and I.A.D., is a law-enforcement agency mentioned in Grand Theft Auto: San Andreas, The Lost and Damned and in Grand Theft Auto Online and appearing in Grand Theft Auto: Chinatown Wars
It is mentioned in GTA San Andreas that Jimmy Hernandez reported the murder of Officer Ralph Pendelbury to Internal Affairs, albeit framing Frank Tenpenny for the killing rather than admitting it was in fact he himself that killed Pendelbury. This leads to Hernandez being murdered by Eddie Pulaski.
