The boy was found with a gunshot wound in a restaurant in the center of Skogås.

He was taken to hospital by ambulance helicopter, but his life could not be saved.

According to sources for SVT, that boy was involved in the recent wave of violence in Stockholm and Uppsala, where two criminal men are waging a violent war over the drug trade in Sundsvall.

On one side of the conflict is the so-called "Kurdish Fox", a 36-year-old convicted criminal who has been in Turkey for some time.

On the other side, a 24-year-old man, leader of a criminal gang in southern Stockholm.

Crime directed at the "Kurdish Fox"

According to the information given to SVT Nyheter, the 15-year-old boy is suspected of having a connection to acts of violence that were indirectly directed at the "Kurdish fox".

The crime must have taken place in recent weeks.

A boy under the age of 18 has been arrested, on probable grounds suspected of aiding and abetting the murder of the 15-year-old.

"Guy we've been worried about"

Reine Berglund was one of the police officers who were called to the restaurant where the boy was shot to death.

He tells Expressen that he recognized the 15-year-old.

- It is terrible.

It's a guy we've had concerns about before, he tells the newspaper.

Max Åkerwall, commanding officer at the Stockholm police, does not want to comment on whether the boy has a connection to the wave of violence, but he says that the police have a "clear picture" of who he was.

Younger people fill the power vacuum

Åkerwall believes that as older gang members have been prosecuted, a power vacuum has arisen in the gangs - a vacuum that younger members have filled.

- We see that young people are the ones who resort to violence in the streets and squares.

Sometimes they do it of their own free will, sometimes out of fear and sometimes because they are forced or threatened by elders to act.

In addition to the murder in Skogås on Saturday evening, two explosions also occurred northwest of Stockholm during the night to Sunday.

And the police expect further crimes in the near future, according to Åkerwall.

- We are doing everything we can to prevent them, but the assessments and analyzes we make together with the intelligence operations suggest that the violence will continue to be at a high level, he says.
