THE scam in Assams veterinary and animal husbandry department first came to light in 1993 when the state finance department discovered excess withdrawal from various treasuries across the state. Alarmed at the development, the Hiteswar Saikia government asked K.S. Rao, then additional chief secretary, to probe the matter. Rao discovered that fraudulent withdrawal in excess of Rs 200 crore had taken place in the veterinary and animal husbandry department aloneall between 1986 and 1992.
