Northern Karelia District Court sentenced a 17-year-old to two years and nine months in prison after convicting him of attempted murder.
The defendant was found guilty of stabbing an acquaintance in the chest at a private residence in late March in the Marjala district of Joensuu, eastern Finland. The victim received life-threatening injuries but is reportedly on the mend.
The court also ordered the defendant, who was 16 at the time of the attack, to pay 12,000 euros in compensation to the victim as well as 3,000 euros in legal fees.
Four youths had gathered at an apartment on the evening of the stabbing in March, according to testimony, and the assailant suddenly stabbed the victim as they were on the balcony.
The assailant then fled the scene, but a police patrol caught up to him about two kilometres from the flat.
During police interrogations the assailant admitted to stabbing the victim but did not explain his motive, and has been in custody since the night of the attack.
