STOCKHOLM // Swedish police arrested four people on suspicion of preparing a terror attack and evacuated an arts centre in Sweden’s second-largest city on Saturday, officials said yesterday.
Sweden raised its terror threat alert level from low to elevated in October last year. In December, a suicide bomber, Taimour Abdulwahab, blew himself up in central Stockholm among panicked Christmas shoppers, injuring two people, causing shock in a country that had largely been insulated from terrorism.
