The 17-year-old was arrested on Wednesday in connection with himself going to the police station and on Saturday he was arrested. 

The attempted murder that the man is suspected of occurred on Tuesday and a man in his 20s was seriously injured but the condition was not life-threatening. 

According to the VLT, the course of events when the 20-year-old was injured must be about four minutes, which appears in the prosecutor's arrest petition. 

SVT has tried to reach prosecutors and the 17-year-old's lawyer without success.
