How to proceed for

Dear Lawyers: My wife is one of the partners in the milk company. They have assigned a supervisor to collects the milk from the agents around the village. It was going smooth, later that supervisor collected the milk from the agents and sold it to others without submitting the bills to the agents. Due to loss, they have stopped the business. The management was asked the agents to submit the bills for the settlement, but they are submitting the fake bills to claim the amount. This case went to the police station as well as Dasildar for a peace meeting, the management clearly said that who all are having the bills with duly signed by the company will ready to settle the payment. Few of them are having with actual bills, but few persons from the agents are not allowing them to get the amount from us. After several discussions, we have requested for Anticipated Bail in the High Cout Chennai, hence they have asked to file a case as FIR. Now the FIR has been filled in the sections of 406, 420, 506(1) and 120B. Moreover, FIR has been filed against my wife(she is the actual partner of the company), myself and my father-in-law. Please advice.
