Hi, I am in urgent need of Professional Help!

I joined a company as Digital Marketing Manager on 1st March, 2018. I worked day & night and got 2 websites ready in 25 days. Based on this performance he offered me the Directorship of 5% for my department. It was all verbal and decided that the directorship will on profit sharing basis without any investment. I was officially introduced as the director but without the shareholding on 12th May, 2018 in MCA. I was happy and continued working with more dedication. Even I delayed my 3 months salary so as to contribute to the company. It was all going fine. Later I got to know the owner's past fraudulent activities through social media. Some of us discussed it with him but he never gave the clear answer and said that the matter is resolved now. We continued further but never got the salaries on time. On 20th Sept, 2018 we all were stressful and some of went to his house. We got to know that he was living with a fake identity and that too police verification is done. I told this to all the staff and got their signatures on the letter mentioning that I was never involved in these activities. I got a majority of signatures and some of them are still with me. Keeping this situation in mind I resigned from the directorship on the day. I continued as an employee for some more days as I was waiting for my 3 months salary. On 27th Sept, 2018, at the heat of the moment, he asked me to resign and I mailed him my resignation on the day and it was accepted on 28th Sept, 2018. 3 more employees resigned on the same day because of the salary issue. He gave the salary date 8th Oct,. 2018 for all the resigned people. Later he gave the date 10th Oct, 2018, Then on 10th he said that the salaries will be credited on 15th-17th Oct, 2018 at the time of company salary date. Today on 15th Oct, 2018, he went to a local police station with an application against me. He mentioned that I am defaming him, affecting his business and brainwashing his existing clients. This existing client cross-verified with me about the company's situation and asked whether he will refund the payment or not. I told everything. Now I want experts to guide me that how can I be safe on the director part. And also how can I get my 3 months salary.
