Well this is just a sad case, then, as even the RTI wouldn't really do much if they are behaving this way, outright uncooperative and unfair. I wouldn't bet too much on this problem to get resolved in the shortest time possible not unless this gets wide coverage and people are made aware of how scummy and how ineffective their investigation process is. I've dug deeper on how investigations such as this happens on India, and most of the time banks are just following the directives of the law enforcement and they pretty much don't have any say on these kinds of investigation.
