The deal that retired banker Kurt manages to get people to invest in looks like this:

Kurt claims that he, along with some others, has accounts abroad with many billions.

Money that should come from successful foreign exchange transactions, land transactions or bond trading.

The "deal" is almost complete.

It only takes a little money to make everyone involved extremely rich.

“Dark number good much larger”

He claims that there are constantly fees that must be paid quickly to close the accounts and transfer money to Sweden.

These are currency fees, taxes and notifications - sometimes of several hundred thousand kronor.

- What stands out is that it is Swedes who are behind it.

It is very unusual.

And if you have found that 100 million have disappeared to these players, then the dark figure is much larger than that, says the police's fraud expert Jan Olsson.

Have you seen this approach before?

- Yes, this approach is modus operandi, the first page of the school book.

This is how it works.

“A negative record”

People have invested everything they have.

The first deposits came as early as 2001 - and it is still going on today.

- That it has been going on for 20 years, it is probably some kind of record even there.

A negative record of course.

I can not remember that I have seen any major fraud actually against individuals made by Swedes, says Jan Olsson.

He says he does not believe there is a legitimate deal at the bottom.

But how can you be so sure that this is an investment scam?

- I'm just saying that it follows the approach of investment fraud to the letter from point to point. And as you say, this has been going on for 20 years, how long do you have to wait to get your money before you can state that it is a investment fraud?

Kurt refers to his lawyer and says that he himself did not make any money on the "deal", when Assignment review confronts him.

He also says that everyone who has invested in the so-called deal will get their money back when the deal closes.
