Car park

So I went exploring in the neighbourhood today and found this huge car park, which kinda scared the shit out of me. It was so dark and old, and I heard this weird noise, like chains were clattering. So I went up to the next floor and found two guys trying to break in to one of the cars. I saw that they saw me so I went really fast towards the exit, and I could hear them following me. Luckily I found the exit fast and got out before they..I dont know, stole my camera? X_X
