The woman called police around 4 o’clock in the afternoon from the Hässelby Strand subway station.
She pointed to a nearby apartment and two young men and a boy were arrested suspected of rape.
“Two of them are 18-years-old and one is 16-years-old,” said police spokesperson Ann-Charlotte Wejnäs to news agency TT.
The woman was taken to Stockholm Söder Hospital’s special department for rape victims.
Technicians planned to inspect the apartment and the police were expected to question the men during the evening, according to Wejnäs.
