In a statement, Team Anna said the construction of dams in Arunachal Pradesh be stopped "as people of Assam cutting across their economic background have been opposing it".
They said the construction activities should stop till an agreement is reached with the people living in the downstream.
They also demanded the alleged police action against protestors be stopped and all those detained released unconditionally.
Gogoi, a Team Anna Core Committee member and general secretary of Krishak Mukti Sangram Samiti (KMSS), is on an indefinite fast along with 30 others since last Saturday as part of anti-dam protests.
Gogoi alleged "police atrocities" have increased and that is why he is sitting on an indefinite fast to press for their demands like release all the detained activists unconditionally and stopping of police attrocities, a statement said.
"India Against Corruption believes that the demands made by Mr. Gogoi must be implemented with immediate effect. IAC urges the government to take immediate steps in this regards. We stand with the activists led by Gogoi in the struggle for betterment of the people in the North East," it said. (more)
