I see this whole building is pretty f'd up by fiery blazes took off everything except some concrete walls. It is in no way to repair again for any potential use without razing it to ground and build a new one.
If I would inspect this place, I would blame the unavailability of fire sprinkler system, there are not much clear pics of the roof, but whatever is there I don't see any water pipes running above the false ceiling.
All he needed was a chainsaw and this image would be springing in the back of my mind.
This is the perfect depiction of a hooligan crossing paths with you. 🤣😅
It's not the first angry bloke who's snapped my car reg, called the police, and likely told, 'there's nothing we can do sir, trespass is not a criminal act'.
