According to NDTV, witnesses revealed that the man suddenly collapsed and, unfortunately, he was declared dead at a nearby hospital.
But according to some reports, there was a delay in providing help despite several others being there at the queue to withdraw money.
"The man was standing in a line. Suddenly he collapsed and we called a local doctor. Later, he was taken to hospital," the security guard posted at the ATM told reporters.
Mr Chowdhury, who worked in the Cooch Behar district, got off a train at Bandel station on the way to his home in Kolkata's Behala area.
He decided to join in a queue at the nearest ATM, hoping to withdraw some money.
Doctors at the hospital said Kallol Roy Chowdhury suffered a heart
attack and was dead by the time he was brought to the hospital. The
incident, which comes just a day after two deaths were linked to
demonetisation queues, took place near Bandel station in Kolkata at
around 7:30 am.
...some ATM queue in India are usually extremely long.
