It was on June 12 last year that the boys, according to the indictment, placed a bomb-like object near the police house's reception in the Garrison area in Linköping.

They also sent an email to the police stating that the bomber was the Hells Angels in Norrköping.

Five days before the boys' bomb alarm detonated the large explosive charge on Ådalagatan.

The boys filmed themselves

In his evidence, the prosecutor has films and pictures taken by the boys themselves and which show how they construct the dummy and then place it.

The consequence of the increase was that virtually the entire old garrison area had to be evacuated for several hours.

In addition to the police, there are also the courts, the public prosecutor's office, the National Forensic Center and the National Board of Forensic Medicine, as well as housing, restaurants and schools.
