Is There Anything I Can Do?

So I have been working for this company for 3 years now. Another department than mine hired a new supervisor and me and him interacted almost on the daily. There are only a few on my shift who speak English, as most of them only speak Spanish. So you kind of make conversation where you can.

Our interactions were pretty general. We joked about work and if it was Friday or not. But something strange happened that I was not expecting. He had put in his two week notice due to a better job offer and I went to congratulate him and ask where he was transferring to. We exchanged numbers. My reasoning was because I thought I might be able to get a job there once he was settled as I'm no longer comfortable at my job. He gave me a goodbye hug, which I didn't think anything of. But once he sat down, he trailed his hand up the back of my leg and grabbed my butt. I stepped away and walked off immediately.

This isn't the first time something has happened. I reported to my supervisor last year about another employee who is over me for making extremely inappropriate comments. Such as looking at me while I was squatted down and saying I was "making him thirsty" and that I had nice legs. Nothing seemed to be done about it.

In fact the very next night (after the supervisor incident) another employee who I had actually flirted with a few years ago (until I found out he was married) tried to grab my hand and I refused him. Later that night I had to help him unclog some product that got stuck. There was no one else in the refrigeration unit with us and he grabbed my butt too.

I was wondering if there is anything that I can do. Since the supervisor is leaving anyway, is there any reason to pursue anything? Or just let it go since he is leaving? Sorry for the long read.
