A long shot, but we had a couple of bags taken from our house last night. Yes... I'm an idiot, i forgot to re-lock the window.
I presume that they've been dumped nearby. Someone found the purse that was in one of the bags - all the cards apart from driving licence had been removed - and returned it to our doorstep.
If anyone finds either of these, do get in touch.
As I said, a long shot. I presume they went in a bin, and it's bin collection day round these parts. So not hopeful.
