Broker fraudulently got us into trouble in a partnership firm

I opened a partnership firm worked for tours and travels. We just started to work in June and met a guy who acted as broker n generated business for us every penny in our current account was send as RTGS to himby us. By end of Aug we started getting police complaints of fraud. The current account got immediately freezed and by start of Sep we came to know that FIR are logged against company. we also got arrested in one case and there is another case running right now and since last 3 yeas we keep getting complaints and police comes to our homes and some time asks for huge amount for bribe. We are stuck in a very bad situation and do not know what to do the only proof we have that we also got cheated is the entire amount in our current account was credited back to that fraud person. Is there a way we can save our self from further cases and above all the current account is under freeze and we want to return all the amount back to customers which is in our current account.
