We will of course look into whether there is any connection between the events, says Malmö police's press spokesperson Nils Norling.
The national bomb squad and technicians have been on site during the night. The police cannot currently say what detonated. Traces have been secured and these will be analyzed.
The blast was directed at the entrance and damage occurred to the entrance door and the facade around it.
The police have initiated a preliminary investigation into general endangerment and serious offense against the law on fire hazardous and explosive goods. No one has been arrested in the matter.
