A man accused of threatening several people with a knife was shot dead on Tuesday in the Norwegian capital Oslo.
"This is a person who was known to us before," a police spokesperson told reporters. "And on that basis we don't see any evidence of a terrorist act, at the same time we don't rule anything out."
Police had been alerted in the morning about a man threatening people with a knife.
When they arrived at the scene the suspect was walking bare-chested and without shoes in the street.
According to the police, they tried unsuccessfully to hit the man with a patrol car, and pin him against a wall.
He then opened the passenger door and injured one of the police officers with the knife.
The police officers shot the attacker, who died a short time later.
