Hr did not help me with resolving my coworker problem

So I have a very entitled coworker who is in thier 60s. They been extorting sex, snacks and money from customers and myself. I told HR and they said they didnt know how to advise me on the issue but would take a report. I have recently been avoiding this coworker but not sure what to do if I run into them again. I applied to a few other jobs and they have yet to call back. What should I do? Also yes I wrote another thread about it and tried contacting HR.
