Three people in their 20s have been arrested after an explosion at a property near Valdemarsro in Malmö's outskirts.
Someone has placed some kind of homemade bomb, says Thomas Paulsson, officer on duty, to TT.
No one was in the residence, a house in a cottage area, when the explosion occurred and caused damage to an outer door.
The incident is classified as aggravated general endangerment and violation of the law on flammable and explosive goods.
According to Sydsvenskan, a house in the same area was subjected to arson at the end of September.
The alarm came in half an hour after midnight and the three suspects are said to have been arrested in the nearby area.
