STOCKHOLM • A masked swordsman who killed a teaching assistant and a teenage boy and wounded two others, all with immigrant backgrounds, was driven by racist motives, Swedish police said yesterday, fuelling concerns that refugee numbers were polarising public opinion in the country.
The 21-year-old assailant walked through a school in Trollhattan, an industrial town in western Sweden with a large immigrant population, stabbing the assistant and the boy to death with a sword before being shot dead by police.
Police said all the victims were from immigrant backgrounds, and Interior Minister Anders Ygeman said record numbers of refugees have fuelled racism among a small segment of society.
The attack came on the same day that the government announced that up to 190,000 refugees could arrive in Sweden this year, a record number that has strained resources. There have also been several arson attacks at asylum seeker centres.
"We will have to ask ourselves several questions about how society is developing, about polarisation, and mobilise all good forces against this racist violence," Mr Ygeman told TV4. "Of course, there is a connection in the sense of the social climate."
But he defended the centre-left's liberal asylum-seeking policies that have seen Sweden accept more refugees per capita than any other European country in recent years. Over the decades, Sweden has welcomed refugees ranging from Vietnam war draft dodgers in the 1960s to Gulf War refugees in the 1990s. "You can't blame the asylum policy because we have a madman who murders children," Mr Ygeman said.
Swedish media said one of the dead, a 17-year-old student at the school, came to Sweden from Somalia three years ago. A 15-year-old, recovering in hospital from stab wounds, recently arrived from Syria.
"Three factors point to the hate crime motive: the way he acted and how he was dressed during the attack at the site, and also findings at the flat where he lived," Trollhattan police spokesman Stefan Gustafsson told Reuters.
In a photo taken after the killer had stabbed at least one person, he posed in a school corridor with pupils who thought his cape, mask and WWII-type helmet were part of a Halloween prank.
Moments later, he stabbed a teacher who approached him. "Then, he chased us through the school. We were terrified," one girl told Swedish daily Aftonbladet.
The killer's alleged social media accounts showed a liking for pro-Nazi video clips and an anti-immigration campaign, said local media.
"We have never felt afraid in Sweden," Aftonbladet quoted the mother of the injured boy as saying.
School attacks are almost unheard of in Sweden - the last incident was near the city of Gothenburg in 1961 when one student was shot dead and six others were injured - and violent crime in general is rare.
Polls show most Swedes welcome refugees. But with up to 190,000 asylum seekers expected to arrive this year, tensions are rising. A number of asylum centres have been attacked in the past week.
Police had to beef up security at centres in August after the murder of a Swedish man and a woman by a refugee at an Ikea store in Vasteras city. The refugee was denied asylum shortly before the attack.
The anti-immigrant Sweden Democrats party has seen its popularity soar, with polls showing it would get about 20 per cent of the vote now, up from around 13 per cent in a general election last year.
