Doctor Binayak Sen is a pioneering medical doctor on community health issues and a leading activist working to ensure the rights of Adivasi (indigenous) and other marginalized communities in the conflict-affected central Indian state of Chhattisgarh. On 24 December 2010, he was sentenced to life imprisonment after being convicted of sedition and conspiracy following an unfair trial. He is currently imprisoned in Raipur central prison, Chhattisgarh. Amnesty International believes that the charges against him are politically motivated and aimed at hampering his work on human rights. He is a prisoner of conscience, and should be immediately released.
