Two bodies were discovered by police in industrial premises in the town of Vallentuna north of Stockholm on Saturday afternoon. Police suspect murder.
Police were led to the bodies by a witness that had seen traces of blood leading into the warehouse building. Two bodies were found and a murder investigation was begun without delay.
When police arrived at the scene a 35-year-old man was also present in the premises, he was arrested and taken to the local police station.
Police doctors have examined the man and DNA samples have been collected from him.
The 35-year-old was interrogated by police on Saturday evening and after the interrogation was completed the prosecutor, Yngve Rydberg, took the decision to charge the man on suspicion of murder with an alternative charge of manslaughter.
Police were unwilling to comment on the investigation or whether the man has a previous record.
A further man was arrested in the vicinity of the warehouse building on Saturday and was taken in for police questioning. He was later released and is no longer part of the investigation.
The area around the premises where the bodies were found has been sealed off by police to enabled forensic technicians to examine the crime scene. Police have been knocking on doors in the area in an attempt to find witnesses to the crime.
The bodies have not yet been identified, according to Lotta Rung at Roslagens police.
Rung reports that a police patrol was in the area on Friday night responding to a call from a nearby property owner.
“A local property owner reported that there was a rowdy atmosphere in the area. A police patrol checked it out, but there was no one found to be in the area at the time,” she said to news agency TT.
It is unclear if the call has anything to do with the murders.
