Today all the houses in Courtenay Street, Courtenay Square and Cardigan Street got stickers on the doors advertising a 24/7 locksmith. The number given is 07932961616. I don't know what other street have been targeted.
This scam was first reported a couple of years ago (using the same number). It is a group of burglars who put them on the doors and then, a few days later, if they have not been removed, reckon that the house is empty. It would be really good if you could let people know, through Kennington News, and ask them to remove the stickers from both their own house and any neighbours.
