According to the chief prosecutor Per Lindqvist, serious crime was averted when the man and woman were arrested on Friday morning.
The suspects, who were arrested on Monday on probable cause on suspicion of being stamped for terrorist crimes, deny the allegations, according to their defenders.
SVT Nyheter has been on site at the apartment where the man and woman are written.
Several neighbors witnessed Friday's attack.
- It was full of black cars in the yard, the parking spaces were not enough.
Then I met masked staff in the stairwell, says Helena who lives in the same staircase.
After she found out via the media what it was about, she feels anxious.
- It's awful.
That you have intervened is fantastic - but also incredibly unpleasant.
"Serious crime has been stopped"
Per Lindqvist, chief prosecutor at the National Unit for Security Objectives, is leading the preliminary investigation.
He does not want to give any details about what the suspects should have planned.
- Through the operation during the Easter weekend, I assess that suspected ongoing serious crime has been suspended.
However, we can not provide any details about any target choices, times, places and other details at the moment, he says.
What made you act?
- There was reason to intervene at this time.
The intervention was completely undramatic when it was done.
According to Per Lindqvist, there is currently no other person deprived of liberty than the two detainees.
