The two derailments are now being investigated by the Swedish police.
They write in a press release that the events are currently classified as sabotage.
They emphasize that they routinely start investigations into such major incidents in this way to be able to make a wider range of investigative moves.
They also write that there are currently no suspects and that they are investigating widely.
"These are serious incidents that have had a major impact on the infrastructure, and in these cases we have started an investigation into a serious crime," says Karin Markaberg, Head of the investigation section at the Norrbotten police district, to the Swedish newspaper DN.
She elaborates to NRK:
"When we have serious incidents like this, both the derailment at the weekend and the one in December, we routinely start investigations in this way to have the opportunity to take the necessary investigative steps, and to be able to cooperate with other authorities such as the Swedish Transport Administration and the Accident Investigation Board to clarify the course of events."
- What makes you classify this as sabotage?
"This is the classification we have chosen now to gain access to our toolbox," says Markaberg.
