I was working on a job in Glasgow town centre, seen a guy in a grey hoodie cycle back and forth about twice every hour or so by the looks of it,thought it was strange and said to a few of the others working there that I thought the place was being scoped out, all looked at me like I was daft, then I was going into the site at half six in the morning the next day as it was a 7 start and just along the road from my digs, watched a man (think it was the person from the day before)walk along the side of the site a few metres in front of me, pull his hoodie over his head and pull the drawstrings to cover his face (the scaffolding actually had a 360 degree dome cctv camera, connected over the internet to a monitoring centre) and he put one hand up and grabbed the top of the fence, vaulted straight up and over in 1 go and about 3 seconds, it was about 8 feet high....went in and told everybody that somebody had just jumped over the fence (when the legitimate site entry gate was only 20 ft away to walk in if supposed to be there) and to watch their tools, the person was already gone as the people on site had a good fast check round to see who was where, a few minutes later it turned out that one of the joiners had lost a nearly new drill and charger complete in its box...must have been in and out of there like a shot and been waiting until after we had unlocked and opened the containers....
