- It was an ambulance that alerted us to an address due to a cardiac arrest in a child, says Johnny Gustafsson, police spokesperson Region East.

The residence where the child was found is cordoned off for a technical examination.

The police are otherwise tight-lipped about the circumstances.

- This is a very tragic case.

We are now investigating the incident as causing the death of another.

This means that you caused the death of another person through negligence, says Johnny Gustafsson.

The adult who was in the home has been arrested on suspicion of causing the death of another and the next of kin have been informed of the death.

- Out of consideration for the victims, I will not comment on who the adult is.

This is a very sensitive investigation for those involved.
