The alleged assaults were to have occurred between 1994 and 2003 and possibly even earlier. The statue of limitations may have expired on several of them, Görts said.
The man was arrested on Thursday but the district court did not find sufficient grounds to remand him into custody and he was subsequently released on Saturday.
“They were of the opinion that the Norwegians can summon him by other means,” said Södertörn prosecutor Nils Lundberg.
