I did some research and also someone from the reddit also said that the funds were reversed not just on hold but it is rare still it is possible. However banks can't reverse a transaction it is only possible when the court passed the order and it comes under the procedure of "returning the stolen property to the rightful owner". And the worst thing is we can't really prove much that we are not involved here since investigation officer may not have any idea about how p2p trading works and you sold something to get the funds in your account but it is what it is and it is only possible to avoid when we can sell our bitcoin directly to exchanges.
