The Swedish woman arrived in Sweden at eleven o'clock on Monday and has been in international demand since 2014. She is in her 30s and a resident of southern Sweden.

She will soon be brought before a detention court at the district court in Lund, where the question of whether the woman should remain in custody will be tried.

The woman is suspected of gross arbitrariness with children.

- At the time when this suspicion arose, she was with her partner.

They were both guardians of the joint child.

Because she went abroad, first then to Turkey and then Syria, we suspect, then she has separated the other guardian from his opportunity to exercise custody of the child, says chamber prosecutor Claudio Gittermann to SVT.

The reason why the crime is classified as serious is because she took the child to an environment that is not safe according to Claudio Gittermann.

There are also suspicions that the woman has joined IS.

- She brought the child to Syria in 2014 when it was a war site at the time and it is not a safe environment for a child.

We suspect that she has connections to IS, says Claudio Gittermann.

The child will be reunited with his father, who is the sole guardian.
