Everyone knew that something was going on, but failed to stop the boy, says SVT's crime reporter Diamant Salihu in Aktuellt.
Parents, social services and police are all said to have been informed that "some form of violent act" was planned by the boy, according to SVT. A few hours later, the shooting occurred.
Expressen has previously reported that the suspected 14-year-old at school said things the same day that indicated he was planning to commit a violent act, but then toned it down by saying he was joking. When his family could not reach him, they became worried and involved both social services and police, according to the newspaper's information.
Social services got in touch with the boy, but he did not want to say where he was or what he was doing, according to Expressen.
The shooting on Södra Kungsgatan occurred just before 02 on the night of Saturday. Six people were hit and injured in the lower body, but none are said to have suffered life-threatening injuries.
The police have stated that the incident is gang-related. However, those who were shot are not linked to gang environments by the police and are not believed to have been intended targets.
