Stalking and harrasement

Respected Sir, There is guy named Aditya Yadav who was there with me in the training in moradabad, who was checking my phone and was causing trouble to me there. He was asking me doubts related to study to which i gave him answers and helped him in return of that he was giving wrong information to my senior that i was not helping him and was causing trouble to me in my work. Now when i came back to kanpur there were such activities like group of people started commenting on me and were harrassing me. In kanpur outside campus also they were doing such kind of activities. Now, due to which i filed a police complaint against them then he said that he will not do it again. For sometime peace was maintained but then again it started. They were following me, deep prakash kushwaha, adtyaprakash mishra and aditya yadav have viralled my photo in whatsapp group and were i don't know what they have written people were stalikng me and harrassing me wherever i was going from the region they belonged, gorakhpur. They used to hit me, abuse me, untidy my clothes deliberately and charged me more money, also in delhi railway station the shops which belonged to the people from their region refused to help me when my phone was to repair. When i was going home from kanpur then also these people were stalking me and harassing me. And know when i was coming back from home(himachal) to my workplace then also these people were doing same kind of activities and were stalking me and harassing me. It seemed that these people were jealous of me and whenever i gets happy and whenever some opportunity comes in my way they just wants to destroy it so they i could not get it. Now in August when i was going from my workplace to home these people were again stalking me what i do , what makes me happy, what angers me and then do these kinds of activities so that i would involve in a fight. And they are constantly harrasing me. In train the people from his region tried to push me out of the train 2 times. and they were hitting me, the guy seemed to be from bihar region was sitting on upper birth was putting his leg on my head deliberately and when i asked him he said sorry bhaiya hame pata nahi tha and again he was putting his leg on my head. With these kinds of activities these people were harassing me. What i should do now i am not able to concentrate on my work. They are spreading rumors about me and causing trouble in my working. Also they are helped by a senior of my from the same region Ashish tripathi to whom i just asked whether you are married and whats your age to which he got very annoyed and started stalking me. It has been more than 1.5 years that these activities are being carried out and they are not stopping.
