Got assaulted by a mechanic (for being from Delhi?)

Today has been the worst day of my life, and I don’t know how much worse things are going to get from here. I went to a local mechanic to get the engine oil changed for my scooter. I specifically asked for Motul Scooter gearless oil, and he said they had it. He drained my scooter’s engine oil, then went somewhere. After a few minutes, another mechanic told me they didn’t have the oil I requested. Instead, they only have oil for manual transmission bikes, which wasn’t suitable for my gearless scooter. I told them they should’ve informed me about this before draining the engine oil. Now, with the engine empty, I had no way to go and get the correct one myself. I remained polite throughout, but things started escalating. The mechanic began cursing at me, saying it wasn’t their responsibility to provide the right oil. He then threatened to put the old, used oil back into the scooter and told me to get the new oil myself. I reluctantly agreed, even as he hurled curses at me, calling me things like “Delhi ke log naamard hote” (Delhi people are not men), “gandu,” and “lawde ke baal” (vulgar Hindi slurs). He apparently noticed my number plate is from Delhi. When he finished putting the old oil back, he suddenly snatched my scooter keys and demanded money. I reminded him that he told me to get new oil, and I wasn’t refusing to pay. But then things turned violent. He tried to pull my scooter away, and when I resisted, he started punching me repeatedly. My mind went blank as he was hitting me. I knew I had to get away, so I grabbed my keys and ran. But he came at me with a wrench. I dodged and ran, but he threw a large stone at me. He broke my scooter’s side mirrors. I called my father, who was in town, to help me. This mechanic shop is only two lanes away from my apartment, and I was terrified. I hid behind a car while calling the police. Before the police could arrive, my father came to find me. When he confronted the mechanic, the situation got even worse. The mechanic gathered some local people and started hitting and abusing my father too. Watching him suffer because of me was one of the most painful moments of my life. The locals kept shouting things like, “Hum local hain, tu kya kar lega?” (We are locals, what can you do?). The police eventually arrived, but even in front of them, the mechanic kept cursing my father and me. The officers told us to pay the mechanic ₹500 and leave. I showed them my injuries (my hand was bleeding) and asked why I was being forced to pay after being assaulted, but they didn’t care. Some people told us, “Don’t mess with this mechanic. He has good terms with the police.” Apparently, there was a police outpost located right in front of the mechanic’s shop, and that’s where the police came from. The mechanic even falsely accused me of vandalizing an old, broken scooter in his shop. That scooter didn’t even have wheels. Despite everything, the police refused to file a proper report. They took photos of my scooter and told us to leave. My father begged them for justice, but they didn’t budge. After we left, I saw the police talking to the mechanic for a long time. I’m terrified they might twist the complaint against me. Now I’m sitting here, covered in bruises, with a bleeding hand and no idea what to do. This mechanic is my neighbor, and he threatened me in front of the police, saying he’d “settle things” with me after they leave. I can’t stop thinking about the locals chanting that I didn’t belong because I’m from Delhi. How is this fair? Does having a Delhi number plate mean I deserve to be treated this way? I can’t stop replaying the events in my mind. I feel like I’ve failed in every possible way. My father had to beg because of me, and he was assaulted because I called him for help. Maybe I should’ve just taken the beating myself and left him out of it. I remained polite throughout the entire incident, never once dropping a single abusive word or resorting to violence. I didn’t even use the word "tu"; I kept addressing the mechanic with "aap" and "sir," showing respect, despite how things were escalating. I’m scared to even step out of my apartment. I’ll likely have to find a new place to live. My career might get ruined if the police turn the complaint against me. I feel trapped and broken. Is this how non-locals are treated here? Why does it feel like there’s no way out?
