Prosecutor: "She refuses a crime"

Later in the morning, on-duty prosecutor Håkan Andersson chose to arrest the woman, suspected of two cases of arson.

- The woman is interrogated and she refuses a crime. Now I'm waiting for answers from the technical investigation to see if we can tie the woman to the deed, says prosecutor Håkan Andersson.

In July it burned at Astern's Preschool and even there, a woman in her 20s is suspected of murder. She is still suspected, but was never arrested because the evidence was considered too weak.

If it is the same woman who is now arrested, Prosecutor Håkan Andersson cannot answer.

- I'm not the lead investigator in that case, so I don't know. It may be the same but it can also be someone else.
