In the first incident, 50-year-old Babu Lal, a resident of Nagla Mansingh here, died due to heart attack after failing to exchange old currency notes despite making persistent efforts at different banks since the past three days, family sources said.
The victim was under tremendous pressure as his daughter's wedding was slated for November 26, they said.
Babu Lal complained of chest pain after returning from a bank yesterday. He was rushed to the hospital, where he was declared brought dead.
They alleged that Idrees had no bank account, but he was making rounds of a local bank to exchange old notes since the past four days.
Local SP legislator Zameer Ullah Khan said both the incidents were connected with the "shock and frustration over failure to get currency notes exchanged" and demanded proper compensation for their families.
