Due to the person's young age, social authorities have been informed and involved.
Why suspicions have been directed against the person is difficult for me to go into. The person is a minor and the case is led by the prosecutor, says the police's press spokesperson Jens Andersson.
The woman was out walking her dog when she was attacked from behind by the person who hit her hard in the back with a sharp object.
She is out walking her dog and when she turns around, she sees, as she herself puts it, a young guy following her. When she turns her head forward again, she suddenly feels a hard blow to her back, said the police's press spokesperson Thomas Fuxborg on Saturday.
The injured woman is still being treated at the hospital on Sunday, but it is unclear how serious the situation is.
The police have increased their presence in the area after the crime for safety reasons.
