The gang was luring people under the pretext of exchanging scrapped banknotes of Rs 500 and Rs 1,000, a Task Force official said, adding they used to charge 10-20 per cent as commission for exchanging the old currency notes.
"We are investigating how these people got the new Rs 2,000 notes when there is a huge scarcity of cash in the market. We may question some bank officials based on the information provided by the arrested persons," the official said.
With reports that some top level police officials were hand-in-glove with currency exchanging gangs in some districts, the state police chief said an inquiry was being conducted into the allegations.
"We will take appropriate action based on our inquiry findings," Sambasiva Rao said.
