We just shut down a huge WWII era manufacturing plant (Fansteel).
We heard an alarm going off one day. The PD took a look around and found nothing, but noticed stuff in dissarray, so they kept an eye on the place.
Turns out there was a gang of 8-10 thieves working the site, including 1 on the roof as a lookout. They would use the old material carts to haul stuff to the far end of the building (2-3 football fields), and then hand-jack it out to a van through a small hole in the 8' fence by the railroad track embankement.
