Somebody vandalized my new bicycle. How do I describe to the police?

I can’t post a picture but just got a bicycle a few days ago. Put it in the communal parking spot with sticker and all.

I go to turn on the battery today and someone cut the wire from the control panel! How would I word this to police ?

I understand they can’t do anything and already talked to my apartment. They can’t help either and I’m so pissed I’m already to knock someone out.
