Finnish investigators probing the damage to a Baltic Sea power cable and several data cables said they found an anchor drag mark on the seabed, apparently from a Russia-linked vessel that has already been seized.

Finnish investigators have linked damage to the Estlink-2 power cable in the Baltic Sea to a Russian-linked vessel, the Eagle S. Anchor drag marks stretching nearly 100 kilometers were discovered, and an investigation is underway to determine intent,

Finnish authorities discovered anchor drag marks on the seabed just a day after it moved the Eagle S to a safer anchorage to help further its investigation.

Finnish police said Tuesday that seven sailors from the Eagle S tanker suspected of last week cutting an undersea power cable between Finland and Estonia are targets of a sabotage investigation and have been banned from leaving the country.
