Gumla, Nov 12 (ANI): Indian security forces have launched a massive anti-Maoist operation in poll-bound Jharkhand to prevent any untoward incident in the election process, stated a senior officer. Jharkhand police officials held a meeting with senior officials of neighbouring Chhattisgarh in one of the worst rebel-infested Gumla districts in the country, which will go to polls on November 25, to devise an effective plan. Deputy Inspector General (DIG) of police, Praveen Singh, assured that electorates wouldn't feel threatened by the ultras. Maoists have called for boycott of the five-phased polls in Jharkhand that begins from November 25 and end on December 20. The results would be announced on December 23. Maoists have killed police and politicians and targeted government buildings in an insurgency that has killed thousands since the 1960s.
