OK, Darren Sims (local police officer) has responded and says...
"NappyValleyNet Hi, sorry for the delay. Could you pass on my email:
northcote.snt@met.police.uk & ask the NVN'r to send me an add & tel no"
"I'll get in touch when I'm back in tomorrow AM..."
"In the meantime keep those doors and windows secure and check out
http://actionfraud.police.uk/"
Obviously if you're really worried then dialling 101 might be an idea but if you can wait until tomorrow then I'm sure Darren will be in contact.
Hope that helps...
