How to vacate premises from st sc tenant

We have rented our property to a person without checking his caste and without rent agreement in January 2018 .He owned the rented property for commercial purpose but later on he started using it for personal use.Initially he asked for some time to pay rent but later on he denied to pay the rent .When we asked him to pay the rent or vacate the house he filled a STSC case as well as FIR against our whole family members in January 2020 .Then we come to know that he belongs to SC ST caste .The STSC case is still under investigation .He also filled a case in Labor court saying that he was working as Driver as well guard and asking compensation for his duties.Here it may be noted that we never hired him as guard or driver and also we were never abused him with his caste names since we were not knowing his caste .He is not ready to vacate the premises and asking money indirectly for doing so .He is also threatening other renters to file a ST SC case against them if they favour us .KIndly help me
