The motive appears to have been that the defendants perceived it as the plaintiff having ruined the relationship between one of the defendants and her boyfriend, says prosecutor Otto Svanberg Ohlsson to the channel.
The incident occurred in November last year. The girl was allegedly lured there under the pretence of meeting someone else, but was instead surprised by the trio who, using threats and violence, forced her to different locations.
According to the indictment, they took turns assaulting the girl, and also subjected her to other forms of humiliation. She was allegedly burned with cigarettes on her forehead and hand, and was also robbed before being released after about two hours.
The evidence against the trio consists mainly of films recorded by one of the girls herself during the course of events.
The trial, which concerns lesser aggravated human trafficking, aggravated assault, robbery, and obstruction of justice, will be held in the Stockholm District Court next week.
