The woman, Violet D'Souza, in her complaint lodged with the Ullal police station here had stated that she got a mail in the name of Royal Bank of Scotland, New Delhi, offering an expensive gift and foreign currencies and the procedures to be followed for this and other expenses involved.
Later, D'Souza also got a call on her mobile with the offer which appeared to be convincing and she transferred Rs 21,58,200 to the account number given by the accused persons.
Investigations revealed that the accused had created a fake website to cheat gullible victims, police said.
A police team led by Ullal police inspector K R Gopikrishna traced the accused, Lalthan Mawia (34), of Mizoram and Khup Boih (32),from Manipur, to Vikaspuri in New Delhi and arrested them on June 10, they added.
