We assess that it's about a hand grenade. There's a lot of shrapnel that has gone off in parked cars and several of them are standing and sounding alarms along the sidewalk, says Ola Österling, press spokesperson at the police.
There is no information that anyone has been injured. Two people have been arrested after a comprehensive police operation in the area, which is located just north of Stockholm's city center.
We have conducted a large number of interviews with people who have made very interesting observations. The evidence is considered good, says Ola Österling.
The site has been cordoned off and the national bomb squad has worked on the site. Next, a technical investigation where they will, among other things, secure tracks.
Have you started to get a picture of why this particular address was targeted?
That work has begun, we have a good situational awareness.
The case is classified as aggravated general endangerment and violation of the law on fire hazardous and explosive goods.
