Bank manager said that he don't have any idea about transaction details. No one called from cyber police regarding same. So only option is to wait for a call from them or for next update from bank. I have read several forums that cyber police freeze updates and no followups after that. In India things are pretty slow.
AFAIK, cyber frauds will be notified to the bank and the bank can only freeze the accounts, so here police cannot freeze your bank account directly and it couldn't happen without the knowledge of bank.Try to contact with higher official and also their support system if it is available.
Better contact a legal advisor in your country to get better advice regarding how to handle this issue.
