Thanks everyone.
Yea, lot of comments here, and I agree with them. I am working again tonight, so will see what I can see on the cctv cameras then. I spoke to the one operators at cctv, but they didn't really want to help me, so I will sort it tonight.
I am actually quite calm still, slept like a baby, no stress, but like you guys said, will have to follow my own advice in future, and like Rolf said, for all I know they will now try and get a gun themselves...
Anyway, thanks again for all of your support. :thumb:
