Nigel Cranswick, a former policeman from South Yorkshire, has been jailed for over ten years today for his part in an attempted £330 million VAT fraud. He and six others, including his sister and brother-in-law, were caught by investigators from HM Revenue & Customs.

They’d set up a business called Ideas 2 Go Ltd and falsely claimed they’d generated billions of pounds in turnover selling mobile phones and computer software.

Much of Bletchley Park’s history involves code-breaking and intercepting radio messages so - when Over The Air 2011 brought hundreds of mobile developers to the site - it seemed appropriate to explore the subject of mobile phone security.

In particular, there were a couple of sessions on the agenda that caught my eye. Detective Sergeant Andy Williams of the National Mobile Phone Crime Unit started by talking about stolen phones... and asking if mobile applications could help with this problem.

The nine men jailed in December 2010 and January 2011 after a £17 million ‘missing trader’ VAT fraud have been joined by four more men.

A further defendant has been charged and is due to stand trial next year.

With mobile phones becoming smarter – and increasing numbers of children using these smartphones – it's not surprising to hear that bullies are taking advantage of mobile technology. 'Cyber-bullying' is now in the Oxford English Dictionary... and some people have even called for a ban on mobiles in schools in an attempt to reduce bullying.
