Tenant not paying deposit and rent and not cooperating

I have a flat in Thane and was staying there. But recently, I relocated to Hyderabad and rented my Thane flat. A tenant moved in on August 02, after the lockdown was relaxed a bit. We got the formal agreement done after collecting his ID and company ID card. A local agent was involved in getting the tenant and processing the agreement. On the day of shifting, the tenant informed me that he was supposed to receive some dues from his company, which is getting delayed. He requested if he can pay the deposit within 7 days of moving in. Since it was covid time, I accommodated his request, being empathetic and understanding. This was August 02. Till today, December 04, he has neither paid the security deposit nor the rent for the last three months. Initially, I was quite understanding and willing to help, but it has crossed all limits when he started telling lies one after the other. In the last three months, he has promised new dates for clearing payment and has failed at least ten times. Every time, he came up with one excuse or the other, cooking up the following stories: • He first blamed it on his company, saying that the company is not paying salary for the last 5 months, even the month of Diwali. This is very unlikely for a company operating in India. • He then claimed to be unwell for 3 weeks pretending to be covid positive and not allowing my people to visit the flat. • Then he said he will sell his car and clear the dues. • Next he said his aunt passed away. • Next he said his father had a heart attack. • Next he said his mother is in comma. • Now again he is saying he will not pay as his company has not paid salary since August. Most of these stories are in mail or whatsapp. Last week my friend visited the flat and rang the bell, but he did not open and when called said he is outside. But my friend spotted him at the flat window from an opposite building. When I informed him that I will contact his company HR, he got really defensive and uncomfortable. All these incidents make me feel doubtful about his whereabouts and raises a question about his integrity as an individual. He has never been apologetic about not keeping up to promises, but rather been very aggressive and abusive as if he has every right to stay in the flat without paying deposit and rent. In the last mail from him, he promised to pay by Dec 04, but when I called today, he said he will not pay now. I have a feeling that he can destroy the furnishings and white goods that have been provided by me inside the flat and move out by saying that he has no money to pay. I seek your help in guiding me how the law safeguards an owner’s interest in such cases – how can I ensure that I get the deposit and the three months overdue rent at the earliest, if he plans to stay. If he plans to move out all of a sudden, how can I get my dues? If I have to evict him, what are the legalities that I need to consider? Do I need to involve the police? What des the law tell me?
