Sweden arrests 3 suspected of preparing "an act of terror"

Swedish officials say three people have been arrested on suspicion of preparing "an act of terror."

Sweden's domestic intelligence agency SAPO says the three were arrested Monday for terror-related activities in several locations in greater Stockholm. SAPO said they had been on the agency's radar for a while.

The agency says several other people have been brought in for questioning.

It added that the terror threat in Sweden remains "unchanged" at a rating of three on a five-degree scale, which is "an increased threat."

In April 2017, an Uzbek man rammed a stolen truck into a shopping crowd in Stockholm, killing five people and injuring 14 others. He said he did it to punish Sweden for joining a coalition against the Islamic State group in the Mideast.
