Fake case of IPC 452 by an advocate neighbour

Hello, Our advocate neighbour filed a fake case against my Father and Mother. My parents and the neighbour had a small argument over the garbage. After the argument they black mailed us for filing the case. After 4 days they filed the case of IPC 452 which actually never happened. Also they gave the date of argument as the same day as the complaint date. Which is totally BS. The advocate neighbour took his friend and his wife as witnesses, who is also an advocate and lives in the neighbourhood. Because their same profession they came to help each other. They still blackmail us on compromising the case. Police filed the FIR after 6 months. Police never arrested my Father or mother but charged us with IPC 452 and other sections. We got the bail. Based on this how can we make our case stronger? Our neighborhood is not so caring for each other. So might not get help from other neighbours. The advocate's son try to get in fight with us. I have his video recorded where he gets abusive and violent. Then there is the date issue of actual incidence and forged date in the complaint. Based on this should move ahead with the case? Or should we gather eye witness?
