Swiss police said they have found no radical Islamist or far-right motives for a gunman who killed himself after a shooting spree at Zurich mosque Monday that wounded three worshippers.
Criminal police chief Christiane Lentjes Meili said investigations were continuing Tuesday in connection with the 24-year-old Swiss citizen behind the shootings.
"There's no indication of any kind of terrorist connection to [ISIS] or an Islamic radicalization of the suspect," Meili said.
An investigation determined that the gunman, who was not identified by name, had also recently stabbed to death an acquaintance, she said.
Two people seriously wounded in the mosque attack were recovering.
