According to Tuesday’s Aftonbladet, the girl is thought to have gone to the flat voluntarily at around midnight on Monday. But police say she was then held there and allegedly raped by several men.
Early on Tuesday morning the girl managed to call the police using a mobile phone and, although she did not know exactly where she was, led officers to the flat. The police broke in at 8.25 on Tuesday morning.
News agency TT reported that the girl was in poor physical and psychological condition when police found her.
“She is being taken care of now,” said criminal inspector Hans Andersson.
“This is one of the most serious cases I’ve seen in this category of crime,” he added.
So far only four people are being held in police custody but an initial search of the flat has revealed “a great deal of suspected stolen goods”. Andersson said that as the investigation progresses more people could be arrested.
