Aggressed in OV

Hey, posting from mobile, sorry for the format. I was on the train yesterday night, going in direction to Vlissingen. The train gets understandably pretty empty once it reaches Zeeland, but there were a bunch of 20-something dutch guys, I think drunk, and very rowdy.

One of them was screaming “ticket!!” at random passengers. I tried to avoid them but this one guy springs in front of me and starts screaming at me. I go towards the head of the train to avoid him and he starts following me all while screaming and banging on the chairs and the doors. This was somewhere between Arnemuiden and Middelburg.

The controllers came out and asked what the fuss was about. Tried to tell them the guy was being violent and that I had to get off at the next stop. They waited with me next to the platform as these guys came out too (and still hurled threats at me) but honestly i havent been okay since then.

The initial shock has worn out. Is there something I could do? Or a police report I could file?

Advice would be appreciated.
