In a pre-dawn three-city operation, Income Tax officials raided at least 50 locations in Delhi and Madhya Pradesh in connection with alleged tax evasions by aides of Chief Minister Kamal Nath. A massive team of around 200 I-T officers and policemen swooped down on the premises of Praveen Kakkad, the Chief Minister's former Officer on Special Duty (OSD), before daybreak. The police claimed that undisclosed cash was recovered during the raids.
