It was at 12 o'clock on Friday that the man went up to the roof, which Borås newspaper was the first to report.
According to Marita Gustavsson, it was via a scaffolding that was used to renovate the institution's kitchen that the man went up to the roof.
- He did it in the form of a protest against employment in institutions and that inmates are forced to take urine samples.
He thinks that is wrong, she says.
For almost eight hours, the man walked around on the roof.
The institution's staff and one of the prison service's negotiators, who, among other things, are trained to have direct contact with inmates in crisis situations, worked hard to get him down.
The man has been taken into care
But it was only when one of the other inmates came to talk to the man that he climbed down.
It was about half past seven on Friday night.
- Now he is taken care of and in safe custody.
The most important thing for us has been that no one should injure themselves and that the man should not jump or fall down, says Marita Gustavsson.
The police were not involved in the case and the man is not suspected of any crime.
On the other hand, according to Gustavsson, the act of climbing up on the roof counts as mismanagement and he may get more days inside the institution.
- It has been a long day for all of us and now the work of investigating this incident continues, says Marita Gustavsson.
