At 16.30 on Thursday, a passenger car drove into a tree in Hässelby in west Stockholm. Four people must have been in the car. Two of them were injured and two of the others must have been infected.

Shortly after 7 p.m., police announced that one of the injured persons had died. The other has been taken to hospital.

Detainees were released - are under 15 years

After looking for the two who left the scene, the police were able to finally arrest them.

"It is impossible to say so much more, but we have started a preliminary investigation into, among other things, gross negligence on the death of another," says Anders Bryngelsson at the police's command center.

However, the two people were later released because of their low age. According to the police, they must be under 15 years.

- Now social authorities have been connected.

Relatives of the deceased person have been notified.
