Sweden never charged him with anything. As the link you've provided clearly states they've issued the "request for interrogation", and since he wasn't available prosecutor gave order for him to be brought in for the interrogation, followed by an Interpol warrant for arrest since he was now in another country. Only after interviewing him Swedish prosecutor would decide whether to proceed with the case and officially charge him with the crime, or would drop the whole thing.
