My Tenant is not vacating neither paying rent

Hi, We have house in bangalore which we rented to my tenant 4 years ago. We are living in abroad. My tenant deposited rent properly for two years. After that he was not paying on time but somehow paid very late by after 10 to 15 days of the rent date. When we called them and asked for the delay he was saying that we are torturing by asking rent and he will vacate the house if we want. Then we asked to vacate the house if he wants to. Seems he didn't expect this response from us and pleased us sayiung he will pay the rent. But he didn't pay rent for the past 6 months and we gave two months notice to vacate the premises. He took one more month extra but still cheating us saying he didn't find the house. He is taking more advantage as we are in abroad and cheating us by not paying rent neither vacating the house. We have planned to do interior work to our home but now we couldn't do anything as they are not vacating. And they are very lethargic and keep saying that we will vacate and we wont eat your house etc. We have proper rental agreement and the agreement also over. And now we dont have any deposit to recover as they are already 6 months rent due. we have plan to come to india for this purpose. Can you please suggest whether i can give complaint in the local police to make them vacate our house? Please help. Thanks, Eswari
