The girl was overpowered by a gang of four boys and three girls when she was on her way to school between 8.30am and 9am. She did not recognise anyone in the gang, but said that they were between 15 and 18, according to the police.
The girl was dragged to the side of Västgötagränd, west of the Biopalatset cinema and raped. Afterwards she managed to get to school where she told the school nurse what had happened. The nurse called the police immediately.
On Monday afternoon the girl was being examined at Söder hospital, where a number of tests were carried out. She will be interviewed again by police on Monday evening.
At the moment police believe she was raped by one person. There was no comment on the role played by the others in the gang.
