How did they really do this fraud? For now I think this is one report is very rare in bitcoin crimes because there is not much news still about bitcoin crimes. A lot of bitcoiner for the moment are very skeptic and tend to be watchful when it comes to scam so the crimes must be very unique and original.
From the article:
The complainant uploaded his information on a local website ‘localbitcoins.com’, he received a call from a Bitcoin dealer Karishma Rajput, her real name is Karishma Rajput. The complainant showed his interest to buy Bitcoin which was then available at the rate of 72,000 rupees per Bitcoin. He wanted to make the payments through Zebpay.com but Karishma Rajput lured him to deal in cash
It looks like the victim was lured into a cash exchange by a dodgy seller...the buyer probably handed over the cash and then the seller never bothered to send the bitcoin to complete the exchange, thus turning it into a fraud/scam case.
