A woman has died and two more have been injured after a series of late night stabbings in Norway.
Shortly before midnight on Tuesday, Norwegian police wrote on Twitter that they had received reports of “multiple people that have been stabbed in multiple locations in Sarpsborg.”
Police later said that three women had been stabbed, with two receiving critical injuries, and that one person had been arrested.
Several Norwegian media outlets reported that one of the women had died of her injuries.
According to broadcaster NRK, one of the victims reportedly recognised the assailant and one person was arrested at an undisclosed address in central Sarpsborg.
The motive was not immediately known, but according to local newspaper Sarpsborg Arbeiderblad, the husband of one of the victims said that the perpetrator had come to their house.
First reports of the attacks came in just before midnight in the city of Sarpsborg, south of the capital Oslo.
Police have arrested a 31-year-old Norwegian citizen who will be questioned today.
A press release said the male alleged attacker had a relationship with two of the women, although not with the woman who was killed.
The victim was in her 50s, police said. Another woman was seriously hurt while a third suffered lighter injuries.
The man arrested will be charged with murder and attempted murder, the statement said.
Police said they were investigating whether the alleged perpetrator’s mental health was a factor in the attacks. The press release said the arrested man had a history of violence but at a later press conference police said this was not in fact the case.
Local media reported armed police, helicopters and nine ambulances were deployed early in the morning in Sarpsborg.
Officers locked down the city centre and asked residents to stay indoors via Twitter.
One woman was stabbed at the central bus station while waiting in her car.
Another was stabbed in her own home. “We were sitting watching TV and there was a knock at the door. When I opened it he tried to stab me, but I got away,” her husband told local newspaper Sarpsborg Arbeiderblad. His wife was then stabbed in the arm.
One of the victims recognised her attacker, which led to the arrest at the man’s home address.
One resident, Ole Martin Gilde, said he witnessed the arrest.
“The police blocked off the street, and I counted up to 12 police cars here,” he told Verdens Gang newspaper. “I also saw up to 10 armed police officers at the intersection here, and then they searched with a dog in all the backyards.”
Police have appealed for witnesses to come forward.
