Fnf clearance pending since four months with a startup.

I was working with a IT startup for better part of the 2018. As it often happens, startups ran out of funds, and so me with other employees were asked to seek employment elsewhere. It has been four months(as of December 2018) and while I have gotten my relieving letter my last month's salary is still pending. The reason I waited for this long before doing anything concrete is because the CEO was trying really hard to get things rolling again and waiting couple of months for my salary felt right thing to do at that time. Recently one of my former colleague informed me that our startup CEO has given up and he will be liquifying his assets really soon. Now that his last efforts are over I asked to clear my account and since then he has started avoiding me, it has been two weeks since he has stopped receiving my calls, reply to my mail queries and keeps delaying our meeting. Do I still have any options after knowingly not asking for my salary for 4 months? Thanks in advance. p.s. I had a legal employment with the company before I was relieved detailing my role, duties and rights with the salary amount, I have also received salaries prior to the month I was let go.
