The arrested woman has a relationship with the boy, according to police, who has launched a preliminary investigation into crime categorization of child autonomy. It was on Thursday afternoon that the six-year-old disappeared and during the night towards Friday a great search effort has been going on - with no results.

- We have started a preliminary investigation with the title of unanimous procedure with children. The woman was interrogated and arrested during the night. She is reasonably suspected and has a relationship with the boy, says Robert Loeffel, the police spokesman.

He emphasizes that you continue to work with unabated strength to find the boy.

- We work on both fronts in parallel. We are definitely not stepping down the search.

The police will continue to search for the six-year-old, which they do in collaboration with the defense force and voluntary organizations.
