Employer not paid salary and other dues

I worked 7.5years in a company as VP-marketing. From last 3-4yrs company did not pay salaries on time. Many employees resigned and I too resigned. But he retained me and only important staff by blackmailing them emotionally, who were critical for running company. He kept promising to pay salaries on time but did not pay. In 2019 he forced me to form a partnership firm in my name so that he can take marketing funds from builders in this firm and funds will be used for salaries of staff only. He assured me that my employment will be continued with his company only and all salaries and benefits will be same as per my employment. He used my firm for his purpose. But still he was not paying salaries on time finally I resigned in Aug 2020 and given handover of all responsibilities. I have been following him for payment, he committed many time but did not pay. Now he is saying you were not my employee so why should I pay you salary. Can I file FIR or legal case against him and how plz guide
