Swedish police arrested four people on suspicion of preparing a terror attack and evacuated an arts center in Sweden's second largest city on the eve of the 9/11 anniversary, officials said today. The four were arrested in Goteborg, said a Swedish police spokeswoman, who wouldn't say whether they were linked to the 10-year anniversary of 9/11. Sweden's terror alert wasn't raised from its current "elevated" status.
"Our assessment is that there is no reason for public concern at the moment," she said. Police in Goteborg said they had evacuated the Roda Sten arts center, located beneath the city's landmark half-mile Alvsborg bridge, due to a threat deemed to pose "serious danger for life, health, or substantial damage of property." The Alvsborg bridge runs over Goteborg's harbor to connect the mainland with the island of Hisingen. The six-lane passage is a vital link from the Norwegian capital Oslo to southern Sweden.
