False rape allegation after 8 years

Hello Sir, I own a farming land where I employed a person in May 2016, as a labour to work in my farm. After giving him 1,50,000, he moved to my farm. The very next day, he again asked to pay him 2,00,000 or he will leave my place. Upon which we refused and he ran away the very next day. Now after 6 or 7 month we filed an application at local police station that such things happend. They brought him in police station and promised to pay later on. After many years of asking for returning money all our efforts went to zero. Finally, in July 2023, we filed an FIR in local police station for cheating. He was brought in and said that I also wants to file an fir for raping my wife. Police refused his request. Then he went to High court and brought a writ directions to Police to investigate the offense. If the offense took place then to file a FIR. Now, during the one day that he lived, I did not go my farm for months because my father were taking care of that. I did not even saw her or met her. The allegation is completely false as I did not even saw her in my farm as I was not going there. Now my farm is 50 km away from my home. What should I do next
