Dehradun, June 15 -- Tension intensified in Dehradun's Vikasnagar area on Sunday a day after a 44-year-old local Bharatiya Janata Party worker was allegedly killed in a clash between members of two communities. While workers from Hindu right-wing outfits and local residents demanded "bulldozer" action and the encounter of the accused, they also pelted stones at the accused individuals' houses and set one of them on fire in Bairagiwala village, police said. An officer familiar with the development said four people have been arrested in connection with the murder and additional police teams were deployed to maintain law and order in the area. The matter stems from an alleged dispute over irrigation water between neighbours in Bairagiwala village, where BJP worker Vinod Kashyap and Imtiyaz got into a fight that escalated into a violent clash around 6.30 pm on Saturday. According to police, Imtiyaz and several others allegedly attacked Vinod and his family. The BJP worker was rushed to a nearby hospital where he died. Dehradun SSP Pramendra Singh Dobhal said: "On Saturday evening, a dispute between two groups in Bairagiwala village under Sahaspur police station limits over irrigation water escalated into violence. The two sides had an ongoing dispute and had exchanged heated arguments over the issue of releasing water into agricultural fields during the past few days. During the incident, members of one group allegedly assaulted three brothers Ashok Kumar, Vinod Kumar and Rajesh Kumar, causing them serious injuries. The injured were taken to Lehman Hospital by local residents, where Vinod Kumar succumbed to his injuries during treatment." After Vinod's death, protesters gathered in the area, demanding "bulldozer action" against the accused's properties and their encounter. Taking action, the administration bulldozed part of another accused individual's house for alleged illegal construction. However the protesters pelted stones at police personnel, demanding that the entire house should be razed, the officer said. Vikasnagar SP Pankaj Gairola said: "The protesters earlier in the day set the house of an accused on fire. After the administration demolished a part of the house of another accused for illegal construction, the protestors were demanding complete demolition of the house, and started pelting stones at the police personnel deployed. We had to use mild force to disperse the crowd." To be sure, the Supreme Court on November 13, 2024, directed that no demolition should be carried out without prior 15-day notice to owner of the property and without following the statutory guidelines....
