On checking the recording, there were apparently two. One came coloured lad sauntered in, with a large rucksack on his back, got no response, maybe didn't knock loud enough - he was followed ten minutes later by a white lad, with no rucksack, whom I heard knock, and he was alert enough, to press the doorbell. I spoke to him, via the window. I saw the latter go in next doors gate, and come out a few minutes later, so they obviously fell for the tale. Both passed from my left, to the right.
A few minutes later, I saw the coloured lad back at my gates, waving to someone, back down the road, and obviously chatting to someone to my left along the road. I would guess that was someone in a van, running them around, to do their begging.
