NHPC office, police station set ablaze, Arunachal BJP chief's house vandalised amid stir over power project

Bamboo barricades put up during a 12-hour shutdown called by various organisations under the aegis of ABKU (Adi Bane Kebang United) across Siang, Upper Siang and East Siang districts over the demand for the release of 10 protesters detained for opposing the construction of a large dam on the Siang River, on October 23, 2026

Amid protests against the proposed 11,200-MW Siang Upper Multipurpose Project (SUMP) in Arunachal Pradesh, a mob torched an NHPC office and a police station, and vandalised the residences of two political leaders, including that of the State BJP chief, in East Siang district, a senior officer said on Saturday (October 24, 2026).

Several police personnel were injured after protesters allegedly hurled stones at them in Pasighat, he said.

The incident took place around 11 p.m. on Friday (October 23, 2026) after a 12-hour bandh to protest against the hydropower project was over, Pasighat Deputy Superintendent of Police Tony Tatak said.

The agitators vandalised the residences of BJP State unit president and former MLA Kaling Moyong, and Pasighat West legislator Ninong Ering, he said.

The office of the Adi Bane Kebang, the apex body of the Adi community, was also ransacked, the officer said.

"The NHPC office in the high region area of Pasighat was set ablaze, while a police station there was also torched," Mr. Tatak said, adding that the authorities were assessing the extent of damage.

The deputy superintendent of police, who was also injured in the incident, said the protesters had come from the Mebo area.

The violence erupted hours after a bandh in Siang, Upper Siang and East Siang districts to protest against the proposed hydropower project was over, he said.

Protesters had clashed with the police in Siang district during the 12-hour bandh against the power project on Friday (October 23, 2026), prompting security forces to fire tear gas shells to disperse the agitators.

Around 150-200 protesters, allegedly armed with machetes, lathis and slingshots, attempted to vandalise police vehicles and breach barricades before pelting security personnel with stones, officials had said.

In East Siang, clashes were also reported near Ranaghat Bridge in Mebo, where protesters allegedly hurled stones at police personnel.

The shutdown was jointly called by the Adi Bane Kebang United, SUMP Affected Area Youth Association, Siang Indigenous Farmers' Forum Youth Wing and Adi Galo Welfare Society.

The organisations are demanding the release of 10 arrested activists, reinstatement of suspended gaon buras (village headmen), withdrawal of all pre-feasibility activities related to the project and removal of paramilitary and central forces deployed in the region.

The Arunachal Pradesh Congress Committee has strongly condemned the violence and demanded an independent inquiry into the use of tear gas shells against protesters during the bandh.

The Arunachal Pradesh government has urged people to exercise caution against unverified rumours, misleading claims and fake news concerning the proposed 11,200-MW SUMP.

The government also appealed to the public to rely on official notifications, press releases and authorised channels for accurate information about the proposed project.

The 11,200-MW project has faced opposition from sections of the locals, amid concerns over its potential impact on the Siang river basin and indigenous communities.

The state government has maintained that the project is primarily intended to store and regulate water in the Siang basin, particularly in view of concerns over China's proposed mega dam on the river.

It also said the project aims to strengthen national water and energy security, manage seasonal floods in the Siang-Brahmaputra basin and promote long-term socio-economic growth.

The government also clarified that activities currently underway are limited to technical and environmental surveys for preparing the pre-feasibility report (PFR) to assess the project's viability.

Emphasising the importance of safeguarding local interests, the advisory said the welfare, rights, land security and cultural heritage of local communities and project-affected families remain central to the government's evaluations.
