Local police dropped me a line recently via their Met Engage initiative regarding a spate of doorstep thefts in the area. I didn't report it to the police as I got a refund but I suppose I should have done. Yesterday, a neighbour came searching for a lost parcel and seemed surprised that doorstep parcel theft was a thing, which somewhat surprised me. Anyway, in case this type of crime is a revelation to anyone else, here's the Met's wholly sensible advice (in future I will be diligent in doing the last one. I imagine that, as very often you can get a refund for non-delivery, this is an under-reported crime and one that I suspect the criminals think is "victimless")
