A man was found stabbed in a cellar in Skärholmen in south Stockholm late on Saturday night.
He was rushed to Karolinska University Hospital in Huddinge with serious knife wounds in his throat and stomach. One person was later arrested in connection with the attack.
“The police are still working at the scene and I can confirm that the victim has very serious injuries,” said Catharina Nordin at south Stockholm police to News agency TT.
In a separate incident a 20-year-old man was stabbed in the back as a fight broke out on Hötorget in central Stockholm at around 10pm on Saturday night.
A man was arrested on suspicion of accessory to murder but was released in the early hours of Sunday morning.
“His explanation satisfied us that we had insufficient grounds to detain the man. But we now have sufficient information to be able to arrest a perpetrator,” said Torgny Wallström at City police to TT.
Soon after 10pm people received a report of a fight at a restaurant near Hötorget. The man was found shortly after on nearby Slöjdgatan and was rushed to hospital in an ambulance with knife wounds.
According to the police his injuries are not life-threatening.
“It is probable that the men knew each other and that there was some form of dispute that began near Sergels square and which escalated and ultimately led to this,” said Torgny Wallström.
