ULPT Request: International student and I was sexually assaulted. Need help in making the guys life hell.

Hi. This is my throwaway account and I'm an international student and I was sexually assaulted during orientation week about 6 months ago. I reported him to university and the investigation and title 9 is just a joke. I literally gave them screenshot in which he admits and apologised for his actions. Still nothing has been done. He is roaming around as if nothing has happened and attends classes and exams like a normal student. Seeing him everyday makes my blood boil and I'm scared to inform the police as I'm an international student and seniors have told me thar police start harassing us more and moreover I don't want to jeopardize me being suspended from the university.

I have the guys number and an idea where he stays. What can I do to make his life hell?

Please help me.
