At least three people were injured, including one critically, in a stabbing attack in southeastern Norway on Friday, Norwegian police said.
A suspect has been arrested, police said on Twitter, without specifying the motive for the attack and saying people appeared to have been attacked at "random".
"At this stage: three people injured and one person critically injured," the police wrote in a tweet.
Minutes later, they said they had the "suspected perpetrator" under control.
The police referred to what they call a PLIVO emergency, meaning an ongoing violent event where lives could be in danger.
The attack occurred in a valley called Numedal just north of Kongsberg, where a man killed five people using knives and a bow and arrow last October.
The trial of the Danish national accused of that attack, who experts say suffers from psychiatric problems, started on Thursday.
