Finnish police said on Tuesday they had recovered a lost anchor from the seabed as part of an investigation of suspected sabotage against power and internet cables in the Baltic Sea.

The Swedish navy said Tuesday it had recovered from the Baltic Sea the anchor of an oil tanker suspected of belonging to Russia's "shadow fleet" and damaging four underwater telecoms cables and one power cable on Dec.

The decision follows a spate of suspected sabotage incidents on underwater cables.

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.

The anchor of the Eagle S oil tanker has been recovered from the bed of the Baltic Sea during an inquiry into the ship's possible involvement in sabotage of maritime energy and communication cables. The EU says the tanker belongs to the so-called Russian shadow fleet.

Finland’s National Bureau of Investigation said the ‘location where the anchor was found is along the route’ of the seized Eagle S tanker

Northern European countries, part of the Joint Expeditionary Force, have enhanced the protection of underwater cables in the Baltic Sea. Artificial intelligence is being used to monitor the Russian fleet.

Finland's Elisa said on Monday that it had finished the repair of its two undersea telecommunications cables that were damaged in the Baltic Sea on Dec. 25. Finland on Dec. 26 seized the Eagle S tanke

Finnish authorities have found and retrieved the anchor of the Eagle S tanker, suspected of damaging cables in the Baltic Sea. Investigators will begin inspecting it on Tuesday. Finnish radio Yle reported that the tanker Eagle S's anchor was located at the bottom of the Gulf of Finland and brought to the surface.
