My roadbike is stolen in Poland - what are my options?

My Trek roadbile (It's a blue Trek. Domane2) was stolen from my front garden in Sayba today.
It's Domane 2 size 52 please please someone help me. As an expat I feel so helpless

Call the police, give them a picture of the bike, bike ID number, etc.

If you know where it was parked, perhaps there are public cameras on the nearby buildings so that the police could review them and possibly find out how it happened.
