He was later exonerated by Bradford police after a 10-month investigation during which his computers were seized and his servers searched. (The investigation was carried out by Bradford police because the formal complaint against him was made from that city.)
At the time David Jack was involved in exposing a number of dodgy finance companies who claimed to be able to get people's debts paid off by exploiting vaguely defined "loopholes" in credit law. However, those people were first asked to make a payment...
Foremost among those companies was Credit Card Killer, so it is interesting to read this BBC News story from September 2012:
A Staffordshire man has been jailed for four years after fraudulently claiming he could clear people's debts.
Basil Rankine, 46, and his wife Amanda, 36, were convicted of a total of 14 offences, including fraud and providing misleading information.
The couple, of Somerset Avenue, Rugeley, made more than £1m in fees through their firm Credit Card Killer by promising to buy up debt.
Amanda Rankine was given a two-year jail sentence suspended for 18 months.
The couple were also banned from being directors of a company for seven years.
