Debnath received the notice only on July 29.
A man committed suicide on Sunday in Assam's Udalguri district allegedly after a local Foreigners' Tribunal recently served a notice on him asking him to prove his Indian citizenship.
Police said Dipak Debnath was found hanging from a tree in the backyard of his house in Ghagra village.
"Preliminary investigation indicate it to be a suicide. His family told us that Debnath was depressed after receiving a notice from the Foreigners' Tribunal which termed him as a foreigner and asked him to prove his Indian citizenship," a police officer said.
Although the Foreigners' Tribunal served the notice to Debnath in July asking him to appear before it on July 12 to prove his Indian citizenship, Debnath received the notice only on July 29.
"The draft NRC was published by the Assam government on July 30 and it included the names of Debnath, his wife and two daughters. However, Debnath went to the Foreigners' Tribunal recently to respond to the notice and a Tribunal official demanded a huge bribe to settle his case," said Uttam Debnath, a nephew of the man.
"We believe he ended his life as he was not in a position to bribe the Tribunal officials. He was scared that he will be taken to detention camps and will be tortured," said Uttam.
The draft National Register of Citizens (NRC) published on July 30 left out the names of 40,07,707 people due to various discrepancies in the documents submitted by the people.
