It is not just SE23 they are targetting, but also Honor Oak, East Dulwhich, Crystal Palace and Sydenham. You can't have two individuals breaking in at the same time in different places.
Many statistics, report the handling of stolen goods, but not burglaries, yet the two things are connected. If criminals are not caught during the act, that is reported under a different name .
The area has been a hot spot for some time. Few months ago, I understand (but not have received) police distributed leaflets in the area warning people to be vigilant.
