Malmö police confirmed to news agency TT that the nine-year-old boy was in the care of a Danish social welfare agency. The whereabouts of his 12-year-old friend are still unknown but authorities believe he is in the area where they found the younger boy - in Jutland, Denmark.
The boys have been in the media spotlight since Monday, when a film clip showed the youngest of them being held down by a security guard at the Malmö central station.
The boys were brought back to the care home from which they had run away, but on Monday, in conjunction with a visit at the Swedish Migration Board in Malmö, the boys disappeared again. They apparently do not speak Swedish.
Daily tabloid Aftonbladet reported that the boys may be brothers. If the older boy is found they will be transferred to Sweden where they can be offered assistance by welfare agencies here.
Aftonbladet had previously reported that the boys absconded from their care home in search of a half brother who they were separated from when they came to Sweden.
