IAS Officer Death: Refusing to yield to mounting pressure for a CBI probe into the mysterious death of an upright IAS officer DK Ravi, the Karnataka Government yesterday announced a CID probe into his death that evoked nation-wide outrage and protests. Amid raging controversy over his mysterious death, a social activist and whistle-blower on Wednesday claimed that the former was planning raids on some big developers to unearth commercial tax evasion.
