The mastermind behind ATM card forgery, who was arrested on Tuesday night from Dhaka's Mirpur area, learned the skill to clone ATM cards from Russia.
The arrested ringleader of ATM card forgery, Shariful Islam (33), went to Russia for higher degrees in 2007.
He got involved in stealing money from ATM booths of different banks through digital forgery after returning home in 2010.
Shariful Islam came up with the revelations during preliminary interrogation after arrest, reports BSS.
The Criminal Investigation Department (CID) arrested him from city's Mirpur area on Tuesday in a case filed over stealing money from the banks through the ATM card forgery.
Meanwhile, a local news agency said, a court in Dhaka granted a four-day remand to interrogate Shariful.
Special Police Super Mollah Nazrul Islam of CID addressed a press briefing at CID headquarters in Malibagh on Wednesday.
The CID official said Shariful confessed his link to the ATM card forgery.
Shariful used to steal information of the ATM card holders using a digital watch having a card reader and converted the information to empty cards.
He then withdrew money from the ATM booths of different banks using the cards, Nazrul Islam said.
"Shariful used to wear wigs and sunglasses while stealing money from the booths," he said.
The CID officials said, Shariful uses a Toyota Allion for his personal use and he has huge amount of money in his bank accounts, he added.
Shariful was jailed for 18 months in two cases filed in 2013.
CID personnel also seized one laptop, 1,400 cloned ATM cards, digital wrist watch used for stealing information of the clients, 14 passports, two mini card reader devices, one wig, one black coloured sunglass and eight mobile phone sets from his possession, Nazrul Islam, said.
"Banks should update their security system as over 100 people are involved in ATM card forgery," Nazrul said.
