The most important reason this seems to happen only in India is that the victims are not in India. So they have to go through their local government and multiple slow processes for the case to be resolved. The unfortunate fact is the prevailing exchange rate difference makes even relatively ordinary western citizens' assets, worth stealing for criminals based here. Also I imagine, such people when defrauded are not in a position to force their authorities to go after criminals not in the same jurisdiction. Or maybe you are suggesting that people from UK are so inherently good that they don't cheat each other at all.
