Corroboration: 3 independent outlets

Scores of citizens, including activist Katon Moyong, were detained by Delhi Police on Saturday, 31 October, during a solidarity protest against the proposed Siang Upper Multipurpose Project (SUMP) at Arunachal Bhavan in New Delhi. The protest was organised by Youth for Change Arunachal and Himkhand. Protesters alleged excessive force, physical and sexual assault during detention. A Himkhand member claimed in a video statement that protesters were beaten, inappropriately touched, and sexually assaulted. Around 25-30 protesters remained detained at Baba Haridas Nagar police station near the Delhi-Haryana border late Saturday. Separately, a solidarity protest was held at Nehru Park Gate in Guwahati on 30 October, demanding cancellation of the project and release of detained protesters. The Arunachal Pradesh Congress Committee condemned the Delhi detentions and demanded the immediate release of protesters, transparency on legal grounds, and a suspension of project activities until community concerns are addressed. Update, 1 November 2026: The Mooknayak reports that around 100 people gathered at the protest, that seven were taken to Chanakyapuri police station, and that an independent journalist, Baksheesh Lamba, was separately detained and later unreachable. It also says protesters demanded an end to the alleged militarisation of the Siang Valley.

## Indian Opinion Analysis

Arunachal24 and The Arunachal Times report the protest and detentions with straight news framing, while The Mooknayak adds the allegation of militarisation in the Siang Valley and names an independent journalist, Baksheesh Lamba, as separately detained and unreachable. The core factual ground is consistent across sources: the protest, the number of detainees, the sexual assault allegation, and the BNSS form. The Mooknayak's additional claim about a missing journalist is not corroborated by the other outlets. The Arunachal Times and The Mooknayak both note women were held past 9 pm, a detail Arunachal24 omits. The Guwahati protest is covered only by Arunachal24, which does not report the Delhi assault allegations. No source reports any official police or government response.
