Three persons including an engineering college dropout, have been arrested from the city by Kolkata Police for their alleged involvement in ATM fraud cases, a police officer said on Thursday.
Two skimming devices, mobile phone, one laptop and pinhole cameras have been seized from their possession, the officer said.
The security guard of an ATM outlet at Elgin Road in South Kolkata caught a man while he was trying to insert a skimming device into the machine last evening, he said.
The security guard who handed over the person to the police, has been awarded for his brave act by the Kolkata Police.
The police arrested the man, who was identified as Rohit Nair, an engineering college dropout from Mumbai.
Two of his associates - Sahil Khan and Sudhir Rajen - were arrested from the airport area and from the CIT Road respectively, the officer said.
Nair and Khan were staying in a south Kolkata hotel while Rajen had put up in an accommodation in Howrah, he said.
"We are trying to find out whether the three persons have any links with the Romanian nationals arrested in connection with the same case," the police officer said.
Nearly 80 customers of nationalised banks in the city have been duped by ATM fraudulent transactions made using cloned debit or credit cards.
The Kolkata Police has formed a SIT to probe into the matter.
Two Romanians have been arrested from New Delhi for their alleged involvement in the ATM fraudulent withdrawal cases.
