Wrong money transfer, now we are in trouble! please advice.

By chance, I got a message i.e 14,000 debited to my salary account. I was badly in need of money, so I thought maybe luck as favored towards me. I thanked myself and spent that money. After a week I got a call from the Bank claiming that it was the wrong transfer of amount, please re-deposit the money to the bank. I just stood dumb after attaining call. Now my concern is what can be done? firstly, whose fault? Now should I take responsibility and trouble to re-return? or shall I escalate the same( I know it is of no use) just want to know what if I don't return will they take any action? My argument is simple it is my bank account.I have all the rights to enjoy all the amount towards same. I believe nobody has right to ask proof for the amount? kindly advice what can be done? looking forward to hearing a sincere feedback on the same.Requesting you to review all the mentioned points. Thank you.
