Misbehavior

I live in a groudfloor flat.. Our house is having 3floor flat. The top most neighbour always park his car in front of our gate and he has 1bike and 1scooty which he parks in our balcony.I have only one Activa yesterday I didn’t get space to take my vehicle out to go somewhere. There was no space to take out the vehicle after asking them to move their vehicle but they didn’t moved, this always happens.. So I was taking Activa out and it crashed with his no plate of the car his no plate has broken but no damage to car.. He came and abused my mother . iam a 16yr boy I live alone with my mother father is in army not posted here.. We called police to complaint about him.. But policed my mother and me to walk to the near by station .. There we talked to asi but he didn't took it seriously and my neighbour was giving false statement he was lying so my mother said 'yr harami sab juth bolra h' the neighbour shouted to hogi harami ' he came to hit my mother with his fist and said ek maarunga yahi behosh kr dunga besharam aurat... The asi shouted on my mother and my mother started crying in police station.. Coz we didn't get justice in front of police and such reaction by police to my mother was intolerable ... While she was crying the munsi of police came and said yaha ro mat hamara dimang kharab naa kr.. Nikal yaha se.. Ye drama krne aayi h yaha.. I told him my mother is suffering from metal problem she is on permanent medicines.. He said why u bringed her here then.. Me and my mother came home crying all the way. As We reached home our neighnour shouted from his floor that aa gye police station se. Hamare waha ki toh jananiya bhi station nahi jaati hamari ijjat h khud ki toh h nahi.. My mother said hum jayenge kya kr lega tu.. He said maar dunga faltu mat bol merse ... It was intolerable for me i shouted maar ke dikha... He came down and removed his chappal to beat me .. Me and my mother rushed into our room.. Police didnt helped us..and Now what should I do.. Plzz help me.
