As we replied earlier:
We see the solution of this situation as follows: the victim provides us with sources of the funds, we provide them to third-party platforms, and if those funds are not of criminal source, we will be unblocked there, and we will unblock client's funds at very the same moment. This is all that is needed to resolve this issue. The victim withdraws the complaint and the homegrown Pinkertons apologize for the insults.
How convenient, freezing 210,000 USDs and demanding the source of the funds, without even disclosing what was the reason to suspect the origin of the money in the first place.
Of course, under this police they have an easy pretext to freeze any customer account with a high balance and plenty of pretexts to refuse any evidence sent as fake in order to keep the money.
And they have the nerve to complaint against people denouncing their actions.
