Kolkata, A team of Nepal Police, assisted by its West Bengal counterpart, has arrested seven persons, including a couple from the state, and seized counterfeit currency having a face value of around ₹70 crore during a raid at a flat near Kolkata, an official said on Monday.

The raid was carried out on Sunday at an apartment within Kamarhati municipality in Belgharia in North 24 Parganas district, where the couple, identified as Deepa Dhar and her husband Arindam, had been living.

Investigators said the couple allegedly contacted businessmen through video calls, showing stacks of fake currency and persuading them to invest money in schemes that promised unusually high returns.
