In the first paragraph, you have written you were terminated because of "ZTP". What is ZTP?
You are eligible to get salary till your last working day (LWD). What was your LWD?
At this stage no need to make police complaint. Write a letter to the MD of your company to release your salary. Send the letter by registered post/AD. Keep the receipt from the post office safe and secure along with the file copy of your letter to MD.
Wait for some time and if nothing happens then make a formal complaint to the Labour Officer (LO) of your area under whose jurisdiction your company falls. You are eligible to approach LO provided you do not work in supervisory capacity. What was your designation? How many persons reported to you?
Please note that LO is different from labour lawyer. Former is government appointed authority whereas latter is individual professional who works in his personal capacity.
When you approach LO, carry with you evidence of your employment like appointment letter, last payslip etc. Please speak in local language in the labour office.
