The situation of the eleven children became known after a notable event in April last year.
In the middle of the night, three thinly dressed and chilled girls knocked on the door of a house in a locality in Dalsland. The girls told that they had been locked in for several months, but had managed to escape.
In the investigation that followed, it was revealed that they and their siblings had been kept away from, among other things, school for a long time, while the family, according to the indictment, moved around to avoid decisions on taking the children into care.
In December, a man and two women were charged, suspected of having kept a total of eleven children isolated from the outside world.
I have not seen anything like this before, that one has been able to keep children away from authorities for so long, said prosecutor Oscar Johansson in connection with the indictment.
"Will appeal"
Two of the accused are parents to ten of the children. However, only the father is convicted in the Göteborg District Court, which sentences him to three years in prison.
According to the court, it is primarily the man who has made the decisions in the family and has had contact with the authorities.
Oscar Johansson does not agree with that reasoning.
I don't buy that explanation, that the mother was completely unaware of this. So I will appeal, he says after the verdict.
Installed transmitters
The other accused woman is the mother of the eleventh child, she is sentenced to probation for gross negligence towards a child in that case.
According to Oscar Johansson, the children, all of whom were minors, were not physically locked in. But they have not been allowed to attend school or, for example, visit the dentist.
Some of the children have been taken into care at times, but have disappeared from their LVU accommodations. On some occasions, the accused are suspected to have placed GPS transmitters on social services' cars and sewn transmitters into the children's clothes.
