An elephant and her one-year-old calf were electrocuted near Dimna lake near here on Monday. The incident occurred when the calf, which was walking ahead of its mother, came in contact with a hanging live wire near the lake. The mother elephant rushed to rescue her child and too came in contact with the wire, divisional forest officer (Dalma wildlife sanctuary), Sidharth Tripathy said, adding both elephants were killed on the spot.
