It was in March earlier this year that the police were alerted to a stabbing in Gottsunda in Uppsala.

A 25-year-old man had been badly stabbed and was taken to hospital after what was described as an altercation that got out of hand. He later died in hospital.

Several people were suspected of being involved in the attack – including a 17-year-old who has been in custody for a long time.

Uppsala District Court has now convicted the 17-year-old of murder.

The teenager is sentenced to juvenile detention for three years and six months and will be deported from Sweden for life after serving his sentence.

Several are acquitted

In total, four people have been detained on probable cause for the murder and for aiding and abetting murder.

Another 37-year-old man is sentenced to one year in prison for aiding and abetting murder as well as assault and aggravated unlawful threats against another person at the scene.

However, the 37-year-old is acquitted of suspicion of aiding and abetting murder.

The two other men, an 18-year-old and a 24-year-old, are acquitted of the charges of aiding and abetting murder and protecting a criminal, respectively.

17-year-old admits knife violence

The 17-year-old's defense lawyer has previously told SVT that the teenager claimed that he acted in self-defense and therefore denied his responsibility for the action.

During the trial, the 17-year-old admitted to using a knife but remains committed to self-defence.
