Police said 150-200 protesters gathered at Dite-Dime, where a clash broke out during the bandh against the proposed hydropower project.
Protesters are demanding the release of 10 arrested activists, reinstatement of suspended gaon buras and withdrawal of project-related preliminary activities.
The Arunachal Pradesh government says the project aims to store and manage water in the Siang basin amid concerns over China's proposed mega dam upstream.
