A witness told local newspaper Göteborgs-Posten (GP) that he heard 10 to 15 shots.
Police cordoned off the area where the shooting occurred and launched a search for the gunmen. The man believed to be the target of the shooting was taken in for questioning.
Asked whether there is any connection to other recent shootings in the suburb, Adlersson said: "It is too early to say but it is likely. These shootings are happening in the same area."
Local residents told P4 Göteborg that they are very worried.
"It is really dangerous for the children and now everybody is thinking moving out of here. It's like living in a war zone," said one resident who did not wish to be named.
Two men in their thirties were arrested in Gothenburg over the weekend on suspicion of weapon crimes. One was detained and the other was released, though he is still a suspect.
It is unclear whether either of the two men were involved in any of the recent shootings in Biskopsgården, but they were arrested in the suburb on Saturday night.
