During January, 32 explosions occurred, primarily in the Greater Stockholm area.
Prime Minister Ulf Kristersson (M) called the many explosions "domestic terrorism".
According to Petra Lundh, several raids, including against bomb makers, have yielded results.
The police's work is incredibly important to interrupt the wave of violence, and what we can see today is that it has calmed down.
It has been over two weeks since the mass shooting in Örebro. At a press conference on Thursday, the police stated that they believe the victims were randomly selected, but have still not disclosed the motive.
In P1-morning, Lundh was asked about the motive behind the deed.
It's not always that you find a motive. What's important now is that we really find all the facts, so that we can put everything on the table. We are mapping this person's life, says Lundh to P1-morning.
If the police are on the track of the motive – or if it may be that we never find out – Lundh does not want to comment, saying that an investigation is ongoing.
Generally, it happens relatively often that you don't find out the motive. We naturally try to get as far as we can, she says.
