I have gone through the same issue, but my Kotak Bank account didn’t get locked. Instead, the person to whom I sent the funds, 19L INR, her account got locked and my account was safe. I’m not going to talk exactly about the source or my background or my online persona. I ended up paying 1L to someone from higher authorities because I knew exactly that if I tried to fight this matter legally, I would end up in an even bigger issue, because honestly and sadly, 90% of the police and higher authorities are corrupt and I am not clean either, So I ended up bribing and got the account unlocked(1L).
sometimes its better to remain under the radar when you have a huge sum of bitcoins sitting in ur wallet since 2013, just be calm and bribe ur way thru...
