SVT Nyheter Skåne has previously revealed how six brothers from Malmö scammed into million agreements in several Skåne municipalities by submitting false documents from their garden companies.
And they have also let unpaid labor work for the municipalities - at the same time as they withdrew millions of kronor to their companies.
One of the people who was attracted by Bosab's ad on Platsbanken was Valentin Lindblom.
He is a trained gardener and was in great need of a job last year.
- I thought that maybe it was something for me, he says.
"Received text message: Do not forget your tools"
Valentin Lindblom quickly understood that the company wanted him to work for free for a few weeks.
- They said they wanted to know who I was.
He was asked to bring his own tools to the workplace, such as chainsaws and climbing equipment.
- I thought it was strange, you can not come up with an unpaid internship and bring your own tools, says Valentin Lindblom.
When he questioned this, he was told that he was no longer welcome.
SVT has searched for the brothers and their companies, but no one has answered our questions.
