The Briefing
- 14 crew members taken into custody
- Cable damaged early Wednesday morning
- Multiple Baltic cables recently affected
Finnish authorities have seized a cargo vessel suspected of causing damage to a telecommunications cable connecting Helsinki and Tallinn, marking the latest in a series of undersea infrastructure incidents in the Baltic Sea region.
The vesselย Fitburg, registered inย Saint Vincent and the Grenadines, was intercepted by the Finnish Border Guard’s patrol shipย Turvaย and a helicopter in Finland’s exclusive economic zone.
Authorities observed the ship’sย anchor chain deployed in the waterย โ a key indicator of potential cable interference.
The Border Guard requested the vessel stop, raise its anchor, and relocate to a safe anchorage within Finnish territorial waters.
The ship was seized shortly after 11:00 AM in a joint operation by Finnish authorities. By late afternoon, it was being escorted towardย Upinniemi.
Finnish telecom operatorย Elisaย detected a disturbance in one of its undersea cables around 5:00 AM on Wednesday.
The damage occurred inย Estonian economic watersย between Helsinki and Tallinn.
Elisa has confirmed that services remain fully operational, as traffic automatically rerouted to alternative paths.
They, however, noted that some customers who had purchased direct transmission connections through the cable may have experienced disruptions.
A repair vessel will assess the damage once weather conditions permit.
Investigation Underway
Theย Helsinki Police Departmentย has assumed lead responsibility for the investigation, taking over from the Gulf of Finland Coast Guard.
Finland’s Prosecutor General has issued a prosecution order, with the case being investigated under charges of:
- Aggravated criminal damage
- Attempted aggravated criminal damage
- Aggravated interference with telecommunications
Multiple Finnish agencies are involved: the Police, Border Guard, Defence Forces, Customs, Traficom, the Finnish Safety and Chemicals Agency (Tukes), and Finngrid.

Regional Pattern of Cable Damage
Estonian authorities report thatย multiple undersea cablesย have been damaged in recent days:
| Date | Cable | Likely Cause |
|---|---|---|
| December 28 | EstoniaโSweden | Storm damage |
| December 30 | Two EstoniaโSweden cables | Storm damage |
| Wednesday | Elisa (FinlandโEstonia) | Under investigation |
| Wednesday | Arelion (FinlandโEstonia) | Under investigation |
An additional cable connectingย Hiiumaa islandย to mainland Estonia was also affected.
The Elisa and Arelion cable damages remain unexplained, while Estonian authorities attribute the earlier incidents to stormy weather.
Estonian prosecutors have indicated they will await the conclusion of Finland’s investigation before deciding whether to launch their own probe or establish a joint investigation team.
Official Response
Finland’s President Alexander Stubbย thanked the Border Guard, police, Defence Forces, Traficom, Customs, Tukes, and Finngrid for their efficient work.
Prime Minister Petteri Orpoย confirmed he has spoken with Estonian counterpart Kristen Michal, noting that authorities in both countries are cooperating well.
Defence Minister Antti Hรคkkรคnenย stated that state leadership is being kept closely informed, with communications handled by agencies under the Ministry of the Interior.
This incident follows heightened concerns over critical infrastructure security in the Baltic Sea. In late 2023, the Balticconnector gas pipeline between Finland and Estonia was damaged under suspicious circumstances, prompting NATO allies to increase surveillance patrols in the region.
The Baltic Sea hosts a dense network of telecommunications and energy infrastructure connecting Nordic and Baltic states, making it a strategically sensitive area.
