Others have been injured in the attacks by a man in the Norwegian town of Kongsberg, local police say.
Several people have been killed and others injured by a man using a bow and arrows to carry out attacks in the Norwegian town of Kongsberg, local police said.
“The man has been apprehended … from the information we now have, this person carried out these actions alone,” police chief Oeyvind Aas told reporters on Wednesday.
“Several people have been injured and several are dead,” Aas said.
Public broadcaster NRK reported at least four people were killed, citing unnamed sources.
According to police, the suspect walked around the city shooting at people with arrows. Several people were wounded in shops, Aas said.
Norwegian police declined to comment on the number of casualties, but said they will investigate whether the attack amounted to an act of terrorism.
“Given how events unfolded, it is natural to assess whether this is a terrorist attack,” Aas told a news conference.
“The arrested man has not been interviewed and it is too early to say anything about his motives.”
The attacks took place over “a large area” of Kongsberg, a municipality of around 28,000 people in southeastern Norway, police said.
Police were alerted to the attack around 6:30pm and arrested the suspect about 20 minutes later. The community is located 66km (41 miles) southwest of the capital Oslo.
Police said the suspect had been taken to a police station in the nearby town of Drammen but gave no other details about the man.
The TV2 station reported that the man also had a knife or other weapons.

Following the attacks, the police directorate said it had immediately ordered officers nationwide to carry firearms. Norwegian police are normally unarmed but officers have access to guns and rifles when needed.
“This is an extra precaution. The police have no indication so far that there is a change in the national threat level,” the directorate said in a statement.
Police urged the public to stay at home and several neighbourhoods were cordoned off, with television footage showing ambulances and armed police in the area.
A helicopter and bomb disposal team were also sent to the scene.
NRK’s website published an image sent by a witness of a black arrow sticking out of a wall.
Norway has traditionally been a peaceful nation but has suffered far-right attacks.
Anders Behring Breivik carried out twin attacks that killed 77 people on July 22, 2011.
Breivik first set off a bomb in the capital Oslo next to the building that housed the office of the prime minister, then went on a shooting spree at a summer camp for left-wing youths on the island of Utoya.
In August 2019, self-proclaimed neo-Nazi Philip Manshaus opened fire into a mosque on the outskirts of Oslo before being overpowered by worshippers, with no one being seriously injured.
However, he had earlier shot dead his stepsister, who had been adopted from China, in what prosecutors termed a “racist act”.
