Doner issue

Hello, My 3 aunty's gifted their property and registered to their 4th sistery mom 9years ago. One aunt passed away 2 years ago and now another aunt( B) being brain washed by other relatives wants her 1/3 share of her property. Since it's not working out she went on giving false complaints to the police station that we are torturing her and that her other sister (A) is physically abusing her, etc. My mom has not taken position of the said property as her 2 unmarried sisters r still staying there but we are paying the taxes. Now that property is being further gifted to me and my brother and registered a year ago. Two days back my (B) aunty physically abused her sister (A)and again went to the station...but since we had put cctv in that house it's being captured and we took that clipping to the station and the police shouted at (B) and told us to give a comaint and we will talk to her and get a letter from her saying she will not do it again. Since they both r old they r not taking it very seriously..we. it was pretty severe almost chocking her neck. We don't know what to do? We want to get rid of this property or atleast this (B) aunt. Its getting very stressful this issue is going on for nearly 5years now. Please advice.
