The extensive drug mess unraveled in May 2018 when two men from the Uppsala region were stopped with five kilos of amphetamine in their car.
The men were arrested on suspicion of serious drug offences, and the trail soon led to the two restaurants in Blekinge.
Together with technicians in protective equipment from the National Forensic Center, the police raided one of the men's restaurant premises and the work of securing traces and evidence went on for several hours.
A few days later, SVT Nyheter Blekinge was able to reveal the first details about the restaurants' spectacular operations.
Later it turned out that at least 150 kilos of amphetamine had been produced on the premises - the equivalent of 1.5 million abuse doses.
Became a climate activist in prison
Despite extensive evidence, the two restaurateurs denied any crime and said, among other things, that they were working on behalf of a secret third party: the so-called "Old Man".
Both were sentenced to long prison sentences, and in a new Spotify documentary, the now 52-year-old ringleader chooses to admit everything.
The reason, he states, is that in prison he partly became a climate activist and partly fell in love.
He also says that he has been a criminal for 30 years of his life.
- I have made a lot of mistakes in my life and now want to benefit and learn from it.
I want to focus on problems other than my own and the climate crisis is the biggest one we have.
The 52-year-old says that he regrets how his past life affected the environment:
- I think, among other things, of all the thousands of miles I've driven by car, he says in the documentary.
