- Latvian police say a vessel inspected in Liepāja is not currently linked to damage to an undersea telecoms cable, though the investigation continues
- The Baltic Sea region has seen several underwater infrastructure incidents recently, raising concerns about maritime safety and geopolitical tensions
What happened: Latvia rules out Liepāja vessel in Baltic Sea cable damage probe
Latvian authorities have announced that their ongoing investigation into damage to an undersea telecommunications cable in the Baltic Sea has not found any evidence connecting a ship docked at the port of Liepāja with the incident. Police completed an inspection of the vessel — examining its anchor, technical equipment and logs, and questioning crew members — but stated on Monday that “the information obtained in the criminal case does not indicate a connection of the specific ship with the damage to the optical cable.”
The damaged cable, which runs between Sventoji in Lithuania and Liepāja in Latvia, was discovered on January 2. Lithuanian officials have confirmed the breach, but the exact cause remains unclear. Latvian Prime Minister Evika Siliņa said the incident has not affected communication services in Latvia.
Criminal proceedings were opened after the damage was reported, and the ship and its crew have been cooperating with the investigation. However, no arrests have been made and the vessel is not being held. Authorities continue to examine the circumstances in which the cable was damaged.
This incident is part of a pattern of undersea infrastructure issues in the Baltic region. Reports indicate other breaches in submarine cables — including one between Finland and Estonia at the end of 2025 — have prompted authorities to interrogate and detain crews in some cases.

Why it’s important
Undersea telecommunications cables are critical infrastructure carrying the bulk of international internet and communication traffic. Damage to these systems can disrupt services, undermine economic activity, and expose vulnerabilities in regional connectivity. While the specific cause of the latest outage remains undetermined, the absence of a link with the inspected vessel underscores the complexity of such incidents.
The Baltic Sea has seen multiple underwater cable and pipeline disruptions in recent weeks and months, contributing to heightened alert among NATO allies and Baltic states. Some analysts and officials view the clustering of incidents with concern, given the geopolitical backdrop of Russia’s invasion of Ukraine and ongoing hybrid security threats. However, experts caution that not all such events can be conclusively attributed to deliberate acts; accidental anchor drags, poor seamanship and natural wear also cause subsea damage worldwide.
The continued police inquiry in Latvia reflects the difficulty in attributing cause, and the wider regional pattern has raised questions about current monitoring and protection measures for subsea infrastructure. Calls for improved technological surveillance of undersea assets and clearer international protocols for cable safety are now part of policy discussions among EU and NATO members. Whether such measures will reduce future risks, or simply add cost and complexity, remains a subject for debate.
