Tenant send us notice through to extend there stay and permit possession of the property

Hi, me and my brother own a property in ludhiana and we stay in UK. My dad signed an agreement on our behalf with our tenant for 12 months. It was due to expireon 9th April 2020 and we asked him month advance to vacate the property to which he started making excuses said we'll leave in months time and then Convid happened. My dad gave them extra month as well. Then they literally refused to vacate the property and said do What you want to do. Then involved police and we had a settllement with the tenants son that they will evacuate on 30th of June. Within three days of that, my dad received notice from court that he has registered case against us and has pledged to court to let them stay there and give him possession of the house. He has mentioned in the notice that my dad was very bad landlord and he was demanding for more money now if we wanted to extend the tenancy and specially because of this lockdown, they have suffered mental torture and they were forced by cops to sign on the blank papers as we knew all the cops. And my mum and dad has been harrasing them and should be compensated as well. Not only that he has even mentioned that we are threatening now his family for life. For some reason head of the panchayat of that area also said that we should not go to our house,(which he says it's his house) any more and just collect rent in the court. We shouldnt force him at all. Now the problem is that we live in UK and can't travel to India specially in this convid 19, how can we get our house evacuated and specially when my dad is the one who was dealing on our behalf. It has given my family lot of stress and don't know what to do about it. I'm open to all advices please. The court date is on 12th of June. Harpreet Singh
