Tenant not vacating rented land, how to get evicting done?

A tenant has rented the 8th room which is not a shop but a store on the ground floor which is behind 7 shops.he was having a dispute with the previous owner and had not paid the rent for last three years before my purchase.As he was not paying i gave him a notice to vacate.in reply he is demanding complete renovation of the subject shop (he is complaining that the shop is leaking) and has refused to pay in future too until this room is completely renovated, in his reply he has threatened that if i fail to do the repair,he will involve accommodation controller/get it repaired /all the expenditure will have to be borne by me.FYI a front side shop is not on his name but on his wife's as per agreement with old owner.she is not doing any business there but this guy is using the front shop as his godown. since he had given me such a reply ,i went after the front shop which is rented on his wife's name and gave her a notice to evict claiming that the shop is being used as godown .
