Chief prosecutor Eva Finné will not pursue an investigation against an officer involved in the shooting who was suspected of involuntary manslaughter.
The fatal shooting took place May 13, when a 68-year-old man was shot and killed by police seeking to conduct a house search. The victim was holding a knife at the time of incident, and had reportedly not responded to a warning shot.
"There is no longer any reason to presume that a crime has been committed. The fatal shot was fired in self-defence," Eva Finné explained on her agency's webpage.
Rami Al-Khamisi, spokesperson for the local commity activist ogranization Megafonen, told Swedish Radio News that the decision to discontine the investigation into the police shooting was a big disappointment.
"I'm not surprised. When the police have investigated other crimes they have committed it also does not lead to anything. That's why we wanted to have an independent investigation by neither the police or a prosecutor."
He also rejects the prosecutors conclusion that the shooting was done in self-defense.
"Is it self defense to shoot an old man?"
During the week following the shooting, rioting by youths in Husby quickly spread to other nearby suburbs, such as Jakobsberg, Hägsatra and Skärholmen. Cars were set ablaze, a police station was attacked and shop windows were broken.
Since 1995, 18 people have been shot to death by the Swedish police according to figures from news agency TT.
Of more than 400 reports of crimes investigated by the police during the riots in Husby and surrounding suburbs of Stockholm, 90 percent of cases have been dropped, reports Swedish Radio News.
