A car exploded Sunday evening while parked outside a block of flats in the Århus suburb of Åbyhøj, reports DR public broadcaster. The force of the explosion shattered six windows and one of the car doors was flung 15 metres from the car itself. Police are at a loss as to the motive of the bombing but have issued a warrant for a 25-35-year-old man seen leaving the scene of the crime. Two other cars were set on fire in the city of Århus, but police believe the episodes are unrelated.
