Need legal advice for charges under ipc 323 , ipc 504 noncognizable counter case

Hi i am a 23 year student , my family recently had some issue with neighours , they were constantly abusing us for having a public water connection pipeline taken through their property . we wrote a formal written complain to the local police station. anyways they continued it and this time more aggresivly . when i went to their house for talking with head of the family. his 21 year old son got physical with me and we had a little fight . nothing serious hurt to both of us. crowd there watched us. this time both familes went to police station . his son has filled a non cognizable offence report under ipc 323 and ipc 504 against me . we also went i have filled the same case against him under ipc 323 , ipc 504 . so its a counter case equally against each other. we both had medical test after that and went home. now i am getting an advice from a friend for the sake of my career. who is in touch with an officer in the police station to give something in writing and submit there in police station( what that may be i have no idea ). there is certainly no dialouge between neighour's son and me to compromise . and i guess this will be single sided from me. thanks for reading all this i need some advice what to give in writing and what not to . any help will be highly appreciated
