The 18-year-old is on probable cause suspected of murder. He has previously admitted that he killed the woman, but denied murder.
It was on the fifth of March that a woman was found dead in a residence in Norrsundet north of Gävle and the police started a preliminary investigation into murder.
A 28-year-old man is charged with protecting the criminal. According to the indictment, he must have helped the murder suspect to get rid of the ax used in the crime, among other things.
