60 people were evacuated while a bomb squad investigated the area closer. No one was injured in the attack.
Swedish Television spoke with residents in the area who were shook up by the attacks.
"When I moved here 32 years ago it was a safe neighbourhood, but now I don't feel safe anymore", says Ioan Lukacs to SVT, "it's just a matter of time before something terrible happens", he added.
The area was cordoned off again in the afternoon to search through a car parked in the vicinity. Police did not find anything suspicious in the car however, and residents have since been let back into their homes, writes local newspaper Sydsvenskan.
