Papadoc, a number of times I have stated already and will do it here again: No lawyer, not even a Malaysian one can force, let alone prompt, a government investigation to reveal any information in an ongoing investigation. It just isn't going to happen. You have to wait for the end of the investigation.
Then, if the information that has been found warrants a court case, then this is the way it will go, and that is when lawyers enter the picture, and only then.
Unless you want to spend your money, only to find out the lawyer is stringing you along, charging while he can. Then, after some time, you will know that there is nothing a lawyer can get from the investigators. They are not allowed to reveal any info before a case gets to court, if it does.
In the meantime, you will have spent a fair amount of money, lawyers aren't cheap, getting no information. But, try it, if you will, and see if you can get what you are looking for. It's your money.
