No personal injuries have been reported, but the detonation, which occurred on Monday evening, caused damage to windows and the façade.
If it had detonated indoors, it would have looked completely different. Fortunately, there was less damage than we feared. It can have a significant impact depending on where it explodes, including a shockwave, among other things, says Erik Creutz, duty officer at Police Region East.
The police suspect that what detonated was thrown at the house. The National Bomb Squad assessed that the residents could stay in the house.
According to information from Norrköping's Newspaper, a teenage boy over 15 years old was arrested in the area where the explosion occurred at one o'clock. He is now suspected of reckless endangerment and violating the law on flammable and explosive goods.
We have conducted a number of interviews and are now reviewing surveillance cameras and checking if there is a threat against anyone in the house. We have secured certain traces, says Erik Creutz.
