Police and emergency services were called to the scene at 11pm on Saturday. The deceased person was found during the extinguishing work, the police write on their website.
– We received the alarm from SOS that someone called them and alerted them that there was a fire and that there should be one person left in the house, so no one raised the alarm because they were passing by and saw the fire, says Fredrik Nilsson, officer on duty at police region North , to TT.
The suspect was arrested in connection with the villa. The deceased has not been identified but is probably a man, according to Nilsson.
The police are tight-lipped about the details of the investigation and refer to it being in an early stage.
