Finnish police said on Sunday they had found tracks that drag on for dozens of kilometres along the bottom of the Baltic Sea where a tanker carrying Russian oil is suspected of breaking a power line and four telecoms cables with its anchor.

Finnish police intend to transport the Eagle S, a Russia-linked tanker the authorities seized after suspecting it of intentionally damaging a Baltic Sea power cable, to shore. The tanker is to be moved from the Gulf of Finland to an anchorage near the Finnish port of Kilpilahti to facilitate the investigation,

The Finnish authorities said the tanker might be part of Russia’s shadow fleet, which emerged as a way to circumvent Western-imposed price caps on Russian oil transported by sea. The caps were introduced several months after President Vladimir V. Putin of Russia ordered the full-scale invasion of Ukraine in February 2022.
