Kolkata, Sept 18: A racket to defraud people by posing as customer care executives of banks and collecting details of their debit card over mobile phone is increasing alarmingly in the city and the police have traced it to Jharkhand.
According to Kolkata Police, at least 450-500 cases of such fraud are reported daily from different police stations in the city.
Investigations into the racket have led Kolkata Police sleuths to Jharkhand, which has become the "headquarters" of such frauds, a police officer said.
"Since last year when the first case of such debit card fraud was reported in the city, it has gone up by leaps and bounds. Now we are getting around 450 to 500 cases every day," said Soumya Banerjee, officer-in-charge of anti-bank fraud section of Kolkata Police's detective department, said.
"Investigation into each case is leading us to Jharkhand from where such fraud is being carried out in thousands and involve 13-year-olds to 30-year-olds, including women," he said.
There are innumerable rackets operating from Karmatar in Jamtara district and Madhupur in Deoghar district in Jharkhand, the officer said.
There are areas along West Bengal-Jharkhand border near Asansol where families have flourished by duping victims across India, he alleged.
The first case of such fraud over phone in the city was reported in July 2014 when a 30-year-old Belighata resident had received a text message from an unknown number that his debit card has been blocked.
Few minutes later he received a call from a person claiming to be a 'customer care executive' of his bank to help him 're-activate' the debit card. This 'customer care executive' sought the details of the man's debit card which he shared with the caller.
Moments later, the man received a text message from his bank that Rs 25,000 had been debited from his account.
