A boy has been sentenced to nine years and four months in prison by Helsinki District Court after being found guilty of stabbing an 18-year-old man to death.
The court found the boy, who was 16 at the time of the incident last October, guilty of manslaughter and aggravated robbery.
His accomplice, another male of the same age, received a four-and-a-half year prison sentence for charges of aggravated robbery as well as aiding and abetting manslaughter.
A third male was also suspected of taking part in the killing, but could not be held criminally liable or charged because he was 14 years old at the time of the incident.
Individuals under the age of 15 are below the age of criminal responsibility in Finland.
The incident took place in the evening of 31 October in Helsinki's Vallila neighbourhood, outside an Alepa grocery store at the intersection of Päijänteentie and Mäkelänkatu.
The court heard that the 18-year-old victim was subjected to violence for an extensive period and attempted to escape several times.
The youth who received the longest prison sentence was found guilty of stabbing the victim at least 20 times.
By the time police arrived on the scene the perpetrators had fled. The victim was taken to hospital but died of his wounds early the following morning.
The main perpetrator was previously convicted of carrying out a robbery in the city last May with another boy.
