How did a man who worked as a petrol pump attendant pull off a ₹670-crore fraud in India?

Nanavath Bhupal Naik, who once worked as a petrol pump attendant and a mason, pulled off a ₹670-crore fraud by luring 7,400 investors with promises of 4% monthly returns from 2022 onwards. Naik used funds from new investors to pay existing investors until the network became unsustainable. He even promised five-gunta land for ₹12.5 lakh with 24% tax-free profit.
