A man in his 40s has been found dead in a residence in Sigtuna municipality. Another man in his 40s, who was in the residence, has been arrested in connection with the death, according to the police.
We received an alarm about a medical emergency and when we arrived, cardiopulmonary resuscitation had begun, but the man's life could not be saved, says Mats Eriksson, the police's press spokesperson.
The police have initiated a preliminary investigation with the crime classification of murder.
The reason we are investigating it as murder is that the circumstances at the scene make it impossible for us to rule out a crime with certainty, says Mats Eriksson, at the Police.
The police will now hold an interrogation with the detainee and conduct a technical examination of the residence.
