@vonny,
This is funny. I'm reading a crime novel right now that's set in Denmark (I know this prison is in Sweden, so, close)
The book was just saying that when non-violent criminals escape, they ususally come back on their own after doing what they needed to do, i.e. a b-day party for a relative. If they don't show up, the police go by their girlfriends or mothers house and pick them up.
