The two youths, Parvez Khan (22) and Rashid (21), both residents of Gaziabab, mostly targeted elderly women and poor people, who usually do not have too much awareness about ATM transactions, said a senior police official.
According to police, the duo followed people at ATM kiosks and read their secret PINs. Once the person after transaction, they would deliberately insert a reserve ATM card in the machine, to generate the message: "Sorry we were not able to read your card. Please insert your card again".
When their targets left after doing so, they would recall the PIN and withdraw money from account.
On Saturday, the police received a tip off that the accused would come to Mukhiya Market in Karawal Nagar, following which a trap was laid and they were arrested, police added.
