It was at 20.30 that the police received an alarm about a sound that was described as firecrackers in Grödinge. When the police arrived at the scene, they found damage to a facade and could establish that there had been a shooting.
Police technicians are now awaited who will investigate the scene.
– We will talk to people we think may have information to give or who have seen something before or after, says Stockholm police spokesperson Towe Hägg.
The police have opened a preliminary investigation into attempted murder and aggravated weapons offences, but no one has been arrested at the moment.
