On his relative's suspicion that it could be a case of suicide, the police earlier searched his residence in Arya Nagar and found a hand-written suicide note, said Station House Officer Devendra Dubey of Swaroop Nagar police station.
In the suicide note, Katiyar said he was consuming poison as he was "unable to bear the pain of his wife's death" and also suffered from multiple incurable diseases, the SHO added.
Dubey said Katiyar's nephew Jyotsin Maisy had told police after his uncle's death that it could be a case of suicide as he was suffering from severe depression after the death of his wife Eva Massy last year.
The post-mortem has been performed and the viscera preserved for further tests to ascertain the exact cause of his death, the SHO added.
