Tenant Issues for commercial building

I have a tenant who runs a medical diagnostic center in my commercial building. He has not paid rent for the last 5 months, not paid water and power back up charges for almost 2 yrs. He has also not paid TDS he has been deducting to the government. When he stopped paying rent citing business losses he gave notice he is vacating and to adjust against deposit. I believe he has rented another property close to mine which is smaller and cheaper. I sent him a legal notice outlining all the payments due which exceeds the deposit. He owes me Rs. 50,000 for utilities, Rs. 2.5 lakhs for TDS not paid and any charges for any damages done to the property or bills not paid to authorities. So about 4-5 lakhs owed which is more than the deposit. The agreement is registered. In reply to my legal notice he did not address any of these charges and instead said I had sent anti-social elements to extort money and other baseless allegations and demanded 25 lakhs in damages He is going to hopefully vacate in 4-5 days. How do I recover this money? 1. Can I stop water and DG services? Any legal implications. 2. Can I lock the front door, seize his properties and demand payment? How do I do this? 3. Is the only option available is to file a case? I do not want this option because it means waiting for a long period and lawyers getting involved
