"A number of preliminary investigation measures have been taken and interviews have been held. Nothing has so far led the investigation forward or been able to provide clarity on who carried out the suspected sabotage," writes the police's press spokesperson Carina Skagerlind to SVT News East.
Furthermore, Skagerlind says that the investigation can be reopened if something new emerges.
It was at the beginning of March that the region's personnel were alerted to the drinking water intake, where they discovered that someone had broken into an electrical cabinet and turned off the pumps.
"The drinking water has not been affected by the suspected sabotage," the region stated in connection with the incident.
