Four people have been arrested in Sweden for plotting a terrorist attack on the 10th anniversary of the 9/11 attacks, according to reports.
Police officials confirmed that a group of people were detained in Gothenburg on Sunday night after the evacuation of a party at the Roda Sten arts centre.
Around 400 revellers were celebrating the opening night of an international contemporary arts festival when police asked the organisers to clear the building because of a terrorist threat. Few other details have so far been released about the incident.
“Around midnight I was called out by the police and they said there was a threat to the building and asked us to quietly stop the party, which we did and everyone left,” Mia Christersdotter Norman, head of Roda Sten, told The Associated Press. “Police have searched the building but they didn’t find anything,” she added.
Sweden’s terror alert level was raised from ‘low’ to ‘elevated’ last year due to an apparent “shift in activities” within suspected terrorist cells in the country. Last December, two people were injured when Taimour Abdulwahab blew himself up in suicide bombing in Stockholm’s busy shopping district.
