Dr Binayak Sen, a medical doctor and human rights defender, was arrested on 12 May 2007. He is currently in prison awaiting a trial that has been repeatedly delayed.
Police allege that he passed letters between imprisoned members of a banned leftist group. However, Amnesty International believe the charges against him are politically motivated, aimed at stopping his human rights work. Dr Sen, a pioneer in providing accessible health care to the rural poor, has been documenting the impact of conflict in the region on the rights of marginalised communities.
The protest was held outside the Royal College of Surgeons in Edinburgh.
