This isn't a problem unique to garthorne road. I work in the area and know of breaks ins all over Honor Oak Park and Forest hill, I know of houses that have been burgled on the roads running off garthorne road. Unfortunately when it's winter and dark break ins and muggins go up. True I posted on here last winter I caught someone breaking into our shed, but again this was happening all around the area which the police confirmed to me and was in the local news.
I posted it as it happened to my neighbour and to remind people to lock your doors.
