Finland's public transport agency said on Wednesday that an oil tanker suspected of damaging undersea cables in the Baltic Sea was found to have serious deficiencies and will not be allowed to operate until repairs have been made.

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.

The Eagle S, thought to be part of Russia’s “shadow fleet,” was detained in December following suspected sabotage.

On Tuesday, January 7, specialists discovered the anchor of the tanker Eagle S at the bottom of the Gulf of Finland. The vessel likely "lost" it during the breakage of several underwater cables, Yle reports.

Finland's national power grid operator said on Thursday it had asked a Helsinki court to seize the Eagle S oil tanker in a bid to secure the company's claim for damages related to the breakdown of the undersea Estlink 2 electricity interconnector.

Finnish authorities investigating damage to subsea power and data cables found drag marks on the seabed likely left by the anchor of seized tanker Eagle S.

Finnish authorities have recovered the anchor of the Eagle S tanker, which is suspected of damaging cables in the Baltic Sea. Investigators will begin their inspection on Tuesday. Finnish radio station Yle reported that the tanker Eagle S's anchor was found at the bottom of the Gulf of Finland and subsequently retrieved.
