The 32-year-old allegedly attacked the other woman in April at the Redbergsplatsen square, located in the city’s Olskroken district.
Having pulled the victim to the ground by her hair, the 32-year-old straddled the other woman and inserted several fingers into her vagina.
According to the indictment, the woman’s actions are tantamount to intercourse meaning that the crime can be classified as rape.
The 32-year-old is also suspected of aggravated assault.
Authorities are reluctant to release many details about the case citing strict confidentiality regulations.
