Dumka, Sept. 30: Dumka forest department may have been successful in rescuing tame circus elephants, but has miserably failed to control increasing man-animal conflict in tribal villages. The threat of elephant attacks increase in this time, when farmers harvest their paddy and brew hadiya to celebrate several festivals. Vairabpur village under Jama block in Dumka recently was attacked by a heard of 17 elephants who destroyed standing crops, stored foodgrain and mud houses. This was the second such attack in the village in the recent past. Twelve days ago, another heard had attacked the same spot, damaging mud homes while trying to raid foodgrain and hadiya stores. Besides, the animals also destroyed standing paddy and maize.
