looks like some small-time criminals in search of some easy cash.
anyway, they have put "high" effort to get into some parts of the building.
the ground floor was easy, there they only needed to pry open a window but they could not use the hallways or the stairs without to trigger the motion detector.
so they have broken loose some wooden beams (they are used as bumpers at the housewall), climbed on top of a lorry and smashed the beams through a window in the upper floor.
unfortunately for them, we rebuild the upper floor and the office was empty.
they have tried to get into other ones as well, but again motion detectors at the hallway.
in the end their only loot were some cigarette packs. this was a bit disappointing. the whole yard is filled with pallets of beverages and not a single crate was missing.
even the money of the vending machine was still there. well they have tried to open it, but they could not break the cash box.
at least they have spared coffee machine
