Thief Simulator 2: Where to Find Your Confiscated Items in the Police Station

Where to find the items confiscated from you when arrested in hardcore mode

Take another left when you get to the room with desks

Your items will be on the floor in the glass room in the corner

I had trouble finding it so I hope this helped!
