Swedish police arrested a woman on Thursday on suspicion of keeping her daughters confined to an apartment amid media reports that they were locked away for a decade. Police suspected the 59-year-old woman had “restricted her children’s freedom… for quite a few years,” spokeswoman Ewa-Gun Westford told newsmen.

According to reports, one of the now adult children managed to briefly leave the apartment in the small southern town of Bromoella and convince a neighbour to call the police, saying that they had been locked up for over a decade.

“The blinds were always pulled down there and we haven’t heard any noise from the apartment,” a neighbour told the paper. Expressen also reported that the woman had moved the children around to different locations in an effort to keep them away from their father.

“One of the young women was led out of the apartment, she could barely walk by herself,” an eye witness told newspaper Aftonbladet. Investigators were questioning the woman and the children — all aged over 18 — at a police station in the nearby town of Kristianstad.
