- The circumstances at the site made it impossible to exclude crime, says Mats Eriksson, press spokesman at the Stockholm Police.

There was a neighbor in the house who sounded alarm to the police at 18 o'clock. Later in the evening, police were able to arrest a person nearby who is now suspected of murder.

- I can't comment if they are familiar, says Mats Eriksson.

Police technicians have been alerted to the scene. Interviews have been held with people on site and during the evening the suspected person will also be questioned.
