Editor,

I write to express deep concern over the recent arrest of individuals in connection with protests against the proposed SUMP in Arunachal Pradesh, particularly following the unrest in Pasighat on and around 23 October.

Among those taken into custody are human rights lawyer and activist Ebo Mili, and youth leaders Otul Jerang and Tajong Talom, along with approximately 26 others (including juveniles) arrested by the East Siang police.

Several prominent activists reportedly surrendered voluntarily and have publicly dissociated themselves from acts of violence, arson, and vandalism. Reports indicate that some detainees have also begun a hunger strike while in custody.

While any violence, damage to public property, or attacks on individuals must be investigated and those responsible held accountable under due process of law, the broader context involves sustained peaceful expression of concern by indigenous communities regarding displacement, environmental impacts, loss of ancestral lands, and the future of the Siang River.

The right to peaceful assembly, free expression, and democratic dissent is fundamental under the Constitution of India. We therefore urgently call upon the authorities to immediately release Ebo Mili, Otul Jerang, Tajong Talom, and all other individuals arrested solely in connection with the anti-SUMP movement and related protests, particularly those who have not been charged with or linked to specific acts of violence.

Review and withdraw cases that appear overly broad, or that risk criminalising legitimate dissent, including any invocation of stringent laws where evidence of violent intent is lacking.

Ensure safety, medical care, and access to legal counsel for all detainees, especially juveniles and those on hunger strike.

Initiate an impartial, independent inquiry into the sequence of events in Pasighat, including the use of force by security personnel and the outbreak of violence. Prioritise meaningful, transparent dialogue with affected communities and protesting groups, rather than relying primarily on security deployments and arrests.

Release of the detainees would help de-escalate tensions, restore confidence in democratic processes, and create space for constructive engagement on the SUMP. Development projects of this scale require the free, prior, and informed consent of indigenous communities and must not proceed through repression of peaceful opposition.

We urge the Government of Arunachal Pradesh to act swiftly in the interest of justice, constitutional rights, and lasting peace in the Siang valley.
