GUWAHATI, Oct. 25 -- Hundreds of protesters opposing the proposed 11,200 MW Siang Upper Multipurpose Project (SUMP) set several government offices and police vehicles on fire, and vandalised the houses of legislators in Pasighat in Arunachal Pradesh's East Siang district on Friday evening, officials said on Saturday. According to officials, the Pasighat office of the National Hydroelectric Power Corporation (NHPC), several government offices, a police station and seven to eight police vehicles were set on fire and damaged by protesters claiming to represent Gen Z. The houses of ruling Bharatiya Janata Party state president Kaling Moyong and legislators Oni Panyang and Ninong Ering were damaged, and some property was taken away by the protesters, officials said. "There was a 12-hour bandh on Friday from 5 am till 5 pm by some people opposed to the project. It went off peacefully in Pasighat, but after 5 pm some protesters calling themselves Gen Z insisted on continuing the bandh and blocked the highway. This caused inconvenience to people and halted traffic. The local magistrate and security forces tried to persuade them for two hours to disperse," said Jayanti Pertin, deputy commissioner of East Siang. "There were several hundred of the protesters. But when they didn't disperse, the magistrate ordered firing of tear gas shells. There was no baton charge. After that the protesters got unruly and started pelting stones which caused hurt to some policemen and officials," she added. Pertin said the protesters then targeted the NHPC office, Pasighat police station and seven police vehicles, which were burnt. Some of them damaged the houses of the BJP state president and the two legislators. "Eight protesters who sustained minor injuries were later given treatment first aid at the local hospital. The situation continued to remain tense till around 4 am on Saturday. Now it is under control," she stated, adding that no one had been arrested till Saturday noon in connection with the violence. Friday evening's violence followed injuries to four women anti-dam protesters earlier that morning after police reportedly fired tear gas shells to disperse protesters at Dite-Dime near Geku. The incident occurred at the 65 Bridge in Dite-Dime, where a large number of people had gathered in support of the shutdown when tensions escalated around 7 am after a group of protesters allegedly attempted to breach barricades and attacked security personnel. Friday's shutdown disrupted normal life across Siang and Upper Siang districts and parts of East Siang, with shops and business establishments remaining closed and residents largely staying indoors. The bandh was jointly called by Adi Bane Kebang United (ABK), SUMP Affected Area Youth Association (SAAYA), Siang Indigenous Farmers' Forum Youth Wing (SIFFYW) and Adi Galo Welfare Society....
