Sweden police make terror arrests
Four people have been arrested on suspicion of preparing a terror attack in Gothenburg, Swedish security police said.
Security police spokesman Stefan Johansson said the four were arrested in Sweden's second largest city early on Sunday.
Mr Johansson declined to give further comments.
It was not immediately clear whether the arrests were linked to the 10-year anniversary of the September 11 terrorist attacks in New York.
Police in Gothenburg said in a statement they had evacuated an arts centre in the city overnight due to a threat deemed to pose "serious danger for life, health or substantial damage of property".
They said they had assisted security police with the arrest and declined to give any further comments.
Sweden raised its terror threat alert level from low to elevated in October last year.
In December, suicide bomber Taimour Abdulwahab blew himself up in central Stockholm among panicked Christmas shoppers, injuring two people.
