INVESTIGATE: Jail fits the bill for ad conman.
HERE'S proof that you should never pay a bill if you don't think it's genuine.
Global conman Michael Petreikis made a fortune by sending invoices to firms saying they'd requested an advert in a business directory.
The directories had plausible names such as The Official Register Of Commerce And Industry and the Hotel And Restaurants Index - but they never existed.
That didn't stop 61-year-old Petreikis netting around pounds 5million from firms in 25 countries, many in the UK.
The happy news is that Petreikis, an American living in Toronto, Canada, is now starting a four-year jail sentence for fraud.
