At least 16 people were arrested in Noida on charges of running a fake call centre and defrauding US nationals.
Uttar Pradesh Special Task Force and sleuths of Gautam Buddha Nagar Police launched a crackdown in a joint operation to nab the accused.
Documents and data related to more than 40 US citizens were also recovered during the crackdown, sources said.
The probe was initiated following a complaint that was received via an e-mail from America. The man alleged that money from his bank account in the US had been fraudulently transferred to an account in a Hong Kong bank after he received a call from the call centre, the STF said in a statement.
The call centre was being operated from a building in an area under the Phase-1 police station in Noida, the statement added.
The STF further said that one of the accused revealed that the gang used to buy data of US citizens, including information about their social security number, following which they called them, thus defrauding them.
Members of the gang in the US ensured that the money derived by fraudulent methods was deposited in accounts of various banks in Hong Kong, it said.
Further investigation is underway.
