The woman who returned to Sweden on Monday after going to an IS-controlled area in Syria has already been questioned by the security police Säpo.

That's what Magnus Ranstorp, associate professor at the Swedish National Defense College, says.

He says that this is the usual approach when IS travelers return.

- One purpose is to see in what psychological state they are in, he says.

About forty investigations

According to Magnus Ranstorp, the police have about forty ongoing preliminary investigations against various IS returnees, with the headings war crimes, genocide and crimes against humanity.

However, proving crimes that have been committed in the places controlled by IS is difficult, and this also applies to the woman from Landskrona.

- If you have no digital tracks or testimonies, it is very difficult to get her convicted of anything, says Magnus Ranstorp.

How dangerous is she now because she previously chose to go to the IS-controlled area in Syria?

- Everyone who has contact with IS can be classified as dangerous, but exactly how dangerous she is can not be said without knowing her psychological state or belief or exactly what she has done down there, says Magnus Ranstorp.

Risk four years in prison

The gross arbitrariness with children that the woman is now in custody on suspicion of can give her four years in prison, if she is prosecuted and convicted.

Magnus Ranstorp assesses that she will continue to be of interest to Säpo even after she is no longer in prison.

- I have a hard time imagining that there will be hidden reconnaissance on her but you will keep track of her, he says.
