On Thursday morning, the Building Congress begins in Stockholm, where representatives from all over the country gather.

It is no daring guess that Joakim Lindholm from Kiruna will get some questions about the attack on the Ore Fields during the congress days.

Joakim Lindholm thinks that it is time for the authorities to take an interest in what is happening around the urban transformations in the Ore Fields, where large construction projects have been underway for many years.

- It is probably better late than never to focus on this.

It can be about everything from environmental crime to pure economic crime.

This kind of thing tends to attract the big projects, he says.

The hope is that the authorities' supervision will result in cases where suspicions of fraud in evidence can be led.

- It will have a deterrent effect, he says.
