"The arrest took place in a calm manner and an interrogation with the person is planned," the text added.

The police raid took place at housing for asylum seekers in Boliden, run by the Swedish Migration Agency.

An unnamed witness told regional newspaper Norran that a man had tried to hide on the balcony, where he was eventually overpowered and arrested by officers.

The man's arrest came a day after authorities revealed a massive hunt was under way for a suspected terrorist, as they raised Sweden's national terror threat alert to record-high levels.

Earlier on Thursday a grainy picture of a man believed to be the suspect was shared widely in media across Sweden. Police told The Local that the same picture had been distributed to officers.

Swedish Prime Minister Stefan Löfven released a statement on Thursday evening, congratulating the service on its work.

"I am impressed by the speed with which it has found and arrested the suspect," it read.
