The police department's special investigations department received a notification yesterday as the police's handling of the seized moped which contained explosives may have been incorrect.
A preliminary investigation into preparation for the general destruction of the destruction is ongoing.
The police announced during a press conference yesterday that the incident means that the police must review their routines.
The moped exploded in a police building in Linköping and now the police are investigating if there are any links between it and the explosion on Ådalagatan earlier in June.
No persons were injured in connection with the explosion.
