I don't think that interpol will have jurisdiction with the case especially if you are the only known victim of that person, they cannot even extradite the hacker to your country for the charges you will be bringing up to them. The only thing you can do right now is to make sure that he won't flush out more money out from you, I still do recommend to clean out your computer even if you have done it right now. Also what others have said about you transferring your money to another bank account is a good idea.
