The blast occurred at a private dwelling on the outskirts of Kungälv, located about 20 kilometres north of Gothenburg, in western Sweden, around 7am on a Monday morning in May.
The explosion, which ripped through the building and tore the 44-year-old man’s thigh to shreds, was caused by the detonation of an explosive device which had been deliberately placed outside the house’s cellar.
Police quickly launched a preliminary investigation into attempted murder.
The injured father of two was immediately flown by helicopter to the Sahlgrenska hospital in Gothenburg for treatment for severe shrapnel injuries.
His wife and one of his two children were in the house at the time of the explosion, but were unharmed.
The wife, along with her 58-year-old lover, were later arrested and remanded into custody suspected of attempted murder.
She was subsequently acquitted but continues to be under suspicion for a separate case of economic crime.
Despite shouldering all the blame for the attempted murder, the 58-year-old man remained adamant that he had only meant to scare his lover’s husband, not to cause him serious injury.
