Across the country, the Norwegian police, who ordinarily are not armed, were given authorization to carry weapons “due to the serious incident in Kongsberg,” the authorities said in a statement late Wednesday. They described it as a precaution.
“The police currently have no concrete indications that there is a change in the threat level in the country,” the statement said.
The police said a suspect was arrested half an hour after the attack began. They did not immediately release information about him.
