Officials say one suspect has been arrested following the incident in Kongsburg on Wednesday and is investigating whether the attack was a terrorist act.
“The man used a bow and arrow for some of the attacks,” Police Chief Oyevind Aas told reporters on Wednesday. Officials are investigating whether other weapons were used, he said.
“That person has been arrested. … From what we have information, this person has only taken these steps,” Police Chief Oyevind Aas told reporters: “It is natural to consider this a terrorist act.”
The chick was injured and taken to a hospital, where he remains in intensive care, an officer on duty and inside the store where the attack occurred, police said.
Mr Aus said the man has not yet been tried and his motive is unknown.
After the raids, the police directorate said it had immediately ordered officers across the country to carry firearms. The Norwegian police are generally unarmed but the officers have access to firearms and rifles when needed.
“This is an additional precaution.
There were attacks on the “large area” of the 28,000-strong municipality of Kongsburg, 66 km (41 mi) southwest of Oslo.
The local time period began around 1810 when the invasion began [1610 GMT]. Police were alerted about the 1830 raid and about 20 minutes later the suspect was arrested.
Eyewitnesses report that the attack began at the Coup Extra Store.
“I can confirm that there was a serious incident on our coupe in Kongsburg,” spokesman Silje Aliso told the tabloid VG.
He said none of his employees were physically injured.
Provisional Prime Minister Erna Solberg described the attack as “horrific” and said it was too early to predict the man’s intentions.
The man was taken to Drummond’s police station but he has not been questioned by investigators, who are still working to determine whether the attack was a terrorist act, he said.
Jonas Gahr Storre, who has been appointed prime minister, is expected to take office on Thursday, responding to the Norwegian news agency NTB calling the attack “a cruel and brutal act.”
Town Mayor Carrie Anne Sand told TV2: “This is a horrific incident, nothing to say. Now we must try to look after as many residents as possible. ”
He said the attack took place in the Westiden area, which has residential, shops and a university campus.
Norwegian Ministry of Justice and Public Security Monica Mayland has received updates on the attacks and is closely monitoring the situation, the ministry said.
City officials invited people affected by the attack and their relatives to join the local hotel for support.
The attack comes a decade after right-wing extremist Anders Breivik bombed an Oslo government district in July 2011, killing eight people. Then he opened fire on the left-wing Labor Party summer camp, a youth organization on Utoya Island, that killed 69 people.
Breivik was sentenced to a maximum of 21 years in prison under Norwegian law, but his time could be extended until he is considered a danger to society.
