Srihar Panda, father of Bidyabharati, the widow of deceased ACF Soumya Ranjan Mohapatra, on Thursday claimed ignorance about the findings of the polygraph tests which his daughter had undergone in Bhubaneswar recently. But he said his daughter is under severe mental stress. Bidyabharati’s father had visited the Livestock Inspectors’ Training Centre in Balangir, where she is appearing for an examination. He said that he came to drop Bidyabharati at the centre as she has been appearing for the Livestock Inspector examinations from Wednesday.
