Frankly, I didn't see any such reports related to Indian bank accounts in recent times! How did you came to know that the accounts are being closed? Can you please share any link or a screenshot of a communication on a similar line? Even I am shocked to know this!
There have been few incidents related to hacked accounts. Where FIR was registered against a few peopl because they had received money from those hacked accounts! I don't know about any other incidents about account closure!
