From the Daily Mail Online:
A student paid £150 for a Blackberry phone which contained the personal details of cabinet ministers, others MPs, civil servants and senior police officers.
Journalism student Darryl Curtis, 44, said he bought the device from a homeless man in Sheffield and found it contained the details of several hundred people.
He said it also held the National Insurance number, home address and computer passwords of a former chief executive of Sheffield City Council, leading him to believe it was once his.
