The detention hearing took place on Sunday afternoon, and the girl denies being an accessory to murder.
She has denied the crime, but otherwise I do not want to say anything about what she has said, prosecutor Lukas Tigerstrand tells TT.
According to the prosecutor, a major crimes investigation team is working "day and night" on the investigation.
"When it comes to detaining such a young person, we are working particularly hard to investigate her. The idea is to be able to replace detention with some type of placement through social services or other measures," he says.
The 24-year-old woman was shot dead on Friday, October 16. At the time of the shooting at the sports facility, both a floorball match and a soccer match were being played nearby, with many people present.
Two teenage boys have previously been detained on suspicion of murdering the woman. Another boy is being detained on suspicion of, among other things, aiding and abetting the murder.
There are a number of suspects and detainees in the case, and as far as we have been able to see so far, we have not been able to see that they knew the victim, says Lukas Tigerstrand.
Another teenage boy has been arrested, but this time in connection with the attempted murder of a completely different person. However, he is a suspect together with the third boy who was arrested in connection with the Älvsjö murder.
