The Swedish BBC, SVT, has a better write up on this that can be ran through whatever translation service your heart desires.
The biggest lie the "European Conservative" is pushing seems to be that they are police staff: The concerned individuals are police students, yet "European Conservative" doesn't mention the word student even once. The students have since been expelled.
It seems at least some already associated with criminal networks when they applied for the police academy.
I'm the first to say that Swedish policing looks like amateur hour at times, but this is just disinformation. I suspect the "European Conservative" is neither European nor conservative.
