"It's in the outside environment and we have technicians in place," Anders Bryngelsson at the Stockholm Police Regional Management Center said.
The woman can be alone worried that he had been raped in Björn park at 23.47 on Friday. In connection with the crime scene, the police could arrest three people who allegedly committed serious rape on Saturday morning.
The police say no more if they are involved rather than the authority of women. He has been taken to a hospital to be treated, and police are looking for more witnesses for the event that has been investigated using dogs and technicians.
