North East charities are currently being targeting by scammers.
Someone will phone to thank you for your involvement or support of some vague community initiative – it may be crime and safety, health, education, etc. – and will thank you on behalf of one of the emergency services.  They will then tell you that they are going to publicise the success of the initiative by distributing a magazine to every house in your area and they will ask you to help contribute to the cost by placing a full or half page advert, which needs to be pre-paid.  Once you send the money, of course, you hear no more.
Please make sure that your staff, particularly your finance teams, are aware of this scam.
