Ajit Mahanta was picked up by personnel of the 13th Gorkha Regiment of the Indian Army stationed in the area.
At about six in the evening, seven people came to Mahanta's bamboo and thatched house where he lived with his mother, wife and two children.
The Army later took his body to the Assam Medical College and Hospital claiming that he died in a fall.
However, the administration turned a blind eye to the situation and did not take the case seriously even after increasing protests.
When the protesters showed no signs of fear, the police and armed forces started indiscriminate firing resulting in the death of nine people.
