On questioning the woman Papiya Sheikh, 26, the officials found that she wanted to come to India for a better life and was forced to carry the currency by their agent, who got them to the city via West Bengal.
Earlier, desperate labourers who wanted to return home from the Middle East were used as carriers. Gangs would send parcels of fake currency and in return, pay for their air fare.
Sources said that gangs send only a few lakhs’ worth of fake currency because there is no major loss if the carrier is caught and agencies are not alarmed.
Sources said the paper quality of these notes is so good that it is hard to pick fake currency.
