release of cheap funds

It means the bank says don't believe fake stories about money sent to India from abroad which is supposed to be in bank accounts and released (paid) to victims in India who pay the criminals money.

It is a type of fraud or scam.

Have you looked up "release" in a dictionary?

Honor Contrex,thank you very much for answering my question .according to your recent remark,does that mean,someone are told that sums of money has been remitted to his or her bank account,but before they get approval for those money from bank,some amount should be charged as commission or fees,for example,in the name of initial deposit,or some other reasons?Could I understand like that?just like the mentioned above.

You understand correctly. It is called an "advance-fee fraud". A well known version is the "419 fraud".

An advance-fee fraud is a confidence trick in which the target is persuaded to advance relatively small sums of money in the hope of realizing a much larger gain. Among the variations on this type of scam are the Nigerian Letter (or 419 fraud) and the Spanish Prisoner.

Thanks for your more detail !

Welcome to A2K.

While the wording of a Internet scam may seem like a riddle to you, you're more likely to get an answer in the English forum.

Of course Contrex is a member of many interests and he gives excellent explanations whatever the forum.

But he never even noticed this was the "riddles" forum. Actually I think the OP had the right idea.

Ah, Contrex. We're a pair of name-dropping soulmates.
