“I have to conduct with the Security Service (Toad) a series of additional inspections at the crime scene,” prosecutor Mats Ljungqvist said in a statement.
The Swedish military to help with the investigation following a request, Ljungqvist added, without giving details of what they were looking for.
Four leaks appeared in late September in the two Nord Stream pipelines in the Baltic Sea off the Danish island of Bornholm, and seismic institutes reported that they had recorded two underwater explosions before the leaks appeared.
While the leaks were in water, two of them were in the Danish exclusive economic zone and two in the Swedish exclusive economic zone.
In early October, the Swedish prosecutor’s workplace announced that he had collected “evidence” from an underwater inspection of leaks in the Swedish economic zone, which had supported suspicions of sabotage.
The new inspection comes as the Swedish military and pipeline owner Nord Stream AG announced earlier this week that they were conducting their own inspections of the burst pipelines.
Jimmie Adamsson, head of communication for the Swedish Navy, said they went to the scene with a vessel specializing in diving operations and supported the new inspection through the prosecutor’s office.
But under pressure that this is not similar to the investigation they had initiated through themselves this week.
“The first investigation did not trigger the second, but they are two separate things,” Adamsson told AFP.
Nord Stream AG, majority-owned through Russia’s Gazprom, said Thursday that a “vessel with special supplies” had reached the area of ”damaged oil pipeline in Sweden’s exclusive economic zone. “
The pipelines, linking Russia to Germany, have been amid geopolitical tensions when Russia cut off fuel supplies to Europe in alleged retaliation for Western sanctions following Moscow’s invasion of Ukraine.
Although they were working when the leaks occurred, they still contained fuel that was spreading in the water and atmosphere.
