An explosion occurred on Saturday evening at a multi-family house in Hjulsta in northwestern Stockholm.
This is the second attack in three days against the same address.
Yes, it's true, it's the same address as the explosion on Thursday and we're looking into whether it's targeted at the same people, says Mats Eriksson, press spokesperson at the Stockholm police.
During the night leading up to Thursday, a hand grenade exploded at the exposed address. Two men were arrested after the incident, but no one was injured in the attack.
No personal injuries have been reported after Saturday evening's explosion. It was still unclear whether it was also a hand grenade.
It is also unknown whether anyone was at the address during the explosion.
We don't know if anyone was home. We're working with resources on site right now, but at present, no one has been arrested, says Mats Eriksson.
