Even policemen have become easy prey for thieves.
Four policemen from Oshiwara police station and 15 others have collectively lost over Rs8 lakh from their bank accounts after some unknown persons cloned their debit cards.
Assistant police inspector S More, one of the complainants and investigating officer, said: "Early on July 27, I received a message from Axis bank that Rs30,000 had been withdrawn from my account from the Federal bank ATM in Dadar. Then I received another message saying that another Rs10,000 had been withdrawn from the State Bank ATM in Dharavi."
More said he realised that the money had been stolen. "I registered a case of forgery against unidentified persons," he said.
He added, "I had not made any withdrawals recently. But I remembered that I had used my debit card at a shop located at Mega Mall in Oshiwara."
"On Tuesday, we detained two salesmen from the store. They had swiped my card four times claiming that there was some technical problem in their system," said More. "I suspect that they copied the CVV number and then passed it on to make a clone card."
A Shastri Nagar resident also registered a complaint alleging that Rs1.5 lakh had been withdrawn from her account without her knowledge.
"We have received complaints from few customers that cash was withdrawn using other bank ATMs. While we are investigating these cases, on August 1, Axis bank filed an FIR with the cyber cell about a device that has been attached to an off-site ATM in Mumbai during a routine examination," said an email from Axis bank.
According to More, the device when attached to an ATM helps hackers get all the information about a card when it is inserted in the card slot.
