Machal Lalung --who spent 54 years in an Indian jail without facing trial.

       Seventy-seven year old Machang Lalung was arrested in 1951 from his native village of Silsang, 64km (40 miles) from the state's main city of Guwahati.Police said that Mr Lalung, who is from the Lalung tribe, was booked for "causing grievous hurt".The offence normally results in 10 years imprisonment.

       But police said there was no evidence to support the allegation, so within a year of his arrest, he was transferred to a psychiatric institution."It seems the police just forgot about him thereafter," says Assamese human rights activist Sanjay Borbora.

       In 1967, the authorities at the institution certified Mr Lalung as "fully fit" and said that they intended to release him.But instead of being freed, police transferred him to another jail."Even at this point, the police did not send him to court to face trial, they just kept him in prison," Mr Borbora said.Strangely, even his relatives and family members forgot about Machang Lalung.

       Lalung died on December 25, 2007. Freedom at the Edge is a short film by Aneisha Sharma, based on Lalung's story.
