Two Dutch teenagers have been sentenced to two years in juvenile detention and three years of compulsory therapy for ordering the death of a girl after an argument on Facebook.
The case, known in the Netherlands as the 'Facebook murder', has caused widespread debate about the role of social media in violent crime.
The victim, identified only as 15-year old Winsie, was fatally stabbed in January at the request of the boy and girl, then aged 17 and 16.
Winsie had argued for weeks with the girl, and they had swapped insults on the social networking site.
The killer, who Dutch media named only as Jinhua and who was 14 when he committed the crime, was sentenced in September to one year in juvenile detention.
