Tenant Reporting False things about the Landlord to the Police.

So a woman who lives on rent in our house is reporting lies about my father to the cops. She came living 2 months ago with her husband it was fine for 10 days or something but then they started fighting each other tho fights happens between married couples but they were too noisy the wife even throws stuffs. So my mom went to them one day and told them to keep it down but the wife started a fight with my mom and told her she barged into her privacy she paid the rent and we have no right of telling them what to do she cursed her, my mom told her to take her money back and find another place to live she said she won't go anywhere few days later we gave her 15 days to find a new place they did agreed on it, but it didn't quiet worked out after 15 days yesterday that was my father got a call from cops asking him to come to the police station when he was there that woman came home and started shouting probably so that we can hear her she was saying stuffs like she will get my father arrested and she will take him to court trap him and those stuffs I missed the opportunity to record it when my father returned she went quiet and he told us he was reported for sexual harassment and threatening to kill her, after a while that day she went to the cops again and this time she told them that my father was trying to beat her in her room, cops called my father again and they were filling the Arrest warrant without even having an solid evidence, somehow the situation got sort out and the woman got 10 days to find another place to live but this morning I heard her talking to her husband that this won't sort things she will get my father arrested at all cost. I'm sure she will try something in these 10 days so I want to know what i can do in this situation.
