When SVT Nyheter Väst meets Joakim Olsson inside one of the Customs Office's warehouses, he is standing in front of a mountain of toys that came by container ship to Gothenburg.

Toys that are not permitted on the Swedish market and that can be dangerous for children.

"Dangerous"

- For example, we have a music box that is meant to hang on the child's bed and that is powered through the wall outlet.

There, the cord is not attached but comes off with a simple pull, then you have 230 volts straight down into the bed, dangerous to life, he says.

It is not only toys that are imported to launder money, but it can be almost any product.

Everything from unapproved medicines and untested beauty products to dangerous toys.

Joakim Olsson says that they have seized over 100 tons since the beginning of the summer alone.

The profit gives white money

According to the head of customs, organized crime is behind the importation of this particular toy mountain.

They launder money by buying goods abroad for black money and then selling them in Sweden.

The profit from the sale can then be taken up as legal income.

How do you know organized crime is behind it?

- We know that, I can't tell you exactly how, but we know that.

We have intelligence and reconnaissance work that works with this, says Joakim Olsson.
