if you park your car in a parking lot, someone told you to move it. Would it be ok for them to open your car and take possesion? No, tow it away to a storage sure.. but damage it no. You have the right to move it, but you also have the legal obligation to prevent damage to it, doesn't matter if he knows or not.
I replace a vendor at a location, and the guy never came to pick his machine up. The owner of the company just moved the machine out to the street and it was vandalized and damaged. The vendor sued owner and me in small claims for the damages, I was released... but the owner who moved the machines, had to pay for the machines contents and damages. Don't get caught up
