Konwar, who has always been in the news for his longevity and seeing his fifth generation, died at his residence from old age related problems, said his family sources.
The Officer-in-Charge of Morigaon Police station confirmed Konwar's age as per a report sent from the police station to the Census Directorate based on the age of his 68-year old eldest great grandson and other family records.
Stating he was active till about two months ago even though his sight and hearing abilities had diminished, the sources said, Konwar's nervous system had failed leading to his death.
Puna Konwar had also come into prominence for casting his vote as the oldest person of the district in the last Assembly election in the state in April 2011.
The average lifespan of people in the remote Baribandha village of the ethnic Tiwa-Lalung community was 90 years, official sources said.
This was attributed by the locals to the unpolluted air and water in their village and consumption of organically grown food.
