The Coast Guard is still on board the Vezhen on Tuesday, which is anchored off Karlskrona.
We are assisting in the preliminary investigation since we have knowledge and experience of vessels, says the Coast Guard's press spokesperson Mattias Lindholm.
He currently has no idea how long the investigation will take.
We are working to be fully available until the prosecutor makes a decision to lift the seizure.
The Task Force Struck
Sunday, January 26, damage was discovered on a data cable between Sweden and Latvia in the Baltic Sea.
New images published by SVT show how the National Task Force struck against the vessel after it was escorted into Swedish waters by the Coast Guard. The Task Force operators were lowered down from one of the Defense Forces' helicopters.
It requires a certain speed and surprise to carry out these operations. Then it's difficult to climb on board a vessel in rough seas, says Engström, explaining the decision to board from the air.
Noa describes the operation as peaceful. The crew was neither handcuffed nor placed in a special room on the vessel during the operation.
There was no violence whatsoever, says Engström.
Suspecting Gross Sabotage
On the same day, the Security Service launched a preliminary investigation into suspected gross sabotage, while the suspected vessel was seized.
Prosecutor Mats Ljungqvist, who is leading the investigation, has previously said that Swedish authorities acted "very quickly" as soon as the suspicion arose and that they have carried out a number of investigative measures.
The Defense Forces in Latvia have sent divers to investigate the damaged cable. The dives are being made to gather evidence for the ongoing preliminary investigation, reports P4 Blekinge.
The Transport Agency has two inspectors on board on Tuesday to check if the vessel meets international safety requirements, writes Blekinge Läns Tidning.
