If you want to keep up to date with things like this and other happenings in your area, most police forces have a system whereby you can get this info sent direct to your inbox, As far as I can see, each force has a slightly different system, so you will have to navigate round their web site.
The more we can pass these warnings on, the fewer people will be taken in by the thieves and villains.
